     DETAILED DESCRIPTION OF THE INVENTION 
     In the following description of embodiments of the invention, reference is made to the accompanying drawings that form a part hereof and in which is shown by way of illustration a number of specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention. 
       FIG. 1  presents a block diagram illustrating one embodiment of a system for providing access to messaging services and content in conjunction with television and TV related content. According to the embodiment of  FIG. 1 , a content distribution server  102  comprises one or more software and hardware components to facilitate the delivery of television and TV related content in conjunction with messaging and messaging related content and services. Hardware and software components include, but are not limited to, a logon component  104 , a messaging component  110 , a TV application component  112 , a profile component  116 , an electronic program guide component  118 , a recommendation component  124  and other applications  122 . The content distribution server  102  also comprises one or more data stores for persistent storage of information used in providing both TV and messaging content and services including, but not limited to, a profile data store  106 , content data stores  114   a  and  114   b , and an EPG data store  120 . 
     The content distribution server  102  is communicatively coupled with a network  100 , which may include a connection to one or more local and/or wide area networks, such as the Internet. Using the network  100 , the content distribution server  102  is capable of accessing local  114   a  and remote  114   b  television content, as well as providing television and messaging services, including combinations thereof, to clients  126   a ,  128   a ,  130   a  and  132   a . The content distribution server  102  is operative to provide TV and messaging content and services to any client device capable of running TV client software  126   b ,  128   b ,  130   b  and  132   b , as well as a messaging client  126   c ,  128   c ,  130   c  and  132   c . For example client devices may include set top terminals  126   a  and  128   a  that use a television as a display device, computer hardware such as a personal computer  130   a  and mobile devices  132   a , such as cellular handsets and personal digital assistants (“PDA”). Other types of electronic communications equipment is contemplated as falling with in the scope of the invention including, but not limited to, digital media adapters, DVD players, connected TVs and other networked consumer electronic devices. 
     When a given client  126   a ,  128   a ,  130   a  and  132   a  initially accesses the content and services that the content distribution server  102  provides, the server authenticates the given user and/or client device. The content distribution server  102  provides a logon component that allows for the authentication of clients  126   a ,  128   a ,  130   a  and  132   a  and/or users of a given client device. A client device  126   a ,  128   a ,  130   a  and  132   a  initializes its TV client application  126   b ,  128   b ,  130   b  and  132   b  and messenger client application  126   c ,  128   c ,  130   c  and  132   c , which initiates the generation and transmission over the network  100  of a logon request to the logon component  104 . According to one embodiment of the invention, the logon request comprises information identifying the user of the client device in addition to information regarding the client device itself, e.g., a MAC address, IP address, phone number or other uniquely identifying descriptor. By providing information regarding the user, the content distribution server  102  may provide a personalized experience to the user regardless of the specific client device  126   a ,  128   a ,  130   a  and  132   a  with which the user connects to the content distribution center  102 . 
     The logon component  104  receives the logon request from a given client  126   a ,  128   a ,  130   a  and  132   a  and attempts to authenticate the user and/or device. The logon component  104  may access a profile  108  for the given user that a profile data store  106  maintains. Accordingly, the logon component  104  uses information identifying the user in an attempt to authenticate the identity of the user, e.g., against information contained in the user&#39;s profile  108 . The identifying information may comprise a username and password whereby the logon component  104  conducts a comparison to ensure that the received password is identical to a stored password. Alternatively, or in conjunction, the logon component  104  may conduct an exchange of public keys with the client  126   a ,  128   a ,  130   a  and  132   a  whereby each device (client and logon component) encodes outgoing data with the received public key and decodes received data with its private key. The logon component  104  may also receive information regarding the client device  126   a ,  128   a ,  130   a  and  132   a , e.g., a MAC address or other uniquely identifying indicia, to authenticate the client device or otherwise validate that the client  126   a ,  128   a ,  130   a  and  132   a  may connect to the content distribution server  102 . 
     The content distribution server  102  may also implement a logon proxy  104   a  to provide scalability and the flexibility to handle large numbers of clients  126   a ,  128   a ,  130   a  and  132   a  attempting to connect to the logon component  104 . Multiple client devices  126   a ,  128   a ,  130   a  and  132   a  initiate communication over the network  100  with a given one of one or more logon proxies  104   a . Each logon proxy  104   a  initiates communication with the logon component  104 , thereby allowing the logon component  104  to service a large number of client requests without the necessity of maintaining and managing a connection with each requesting client  126   a ,  128   a ,  130   a  and  132   a.    
     Where the logon component  104  is unable to successfully authenticate the user or client  126   a ,  128   a ,  130   a  and  132   a , the logon component  104  prevents the client  126   a ,  128   a ,  130   a  and  132   a  from accessing functionality that the content distribution server  102  offers. Alternatively, the logon component  104  may solely provide access to the TV application component  112 , electronic program guide component  118  and EPG data store  120 , thereby allowing the user to view TV content and scheduling data on the client  126   a ,  128   a ,  130   a  and  132   a . A user whom the logon component is unable to authenticate is therefore presented with a traditional digital TV content viewing experience with content from one or more content sources  114   a  and  114   b , as well as program guide data for his or her locality. 
     Where the logon component  104  successfully authenticates the user and/or client device, the logon component may record an indication of the successful authentication in the user&#39;s profile  108  in the profile data store  106 . The logon component  104  provides an indication to the messaging server  110  and the TV application component  112  that the user and/or client  126   a ,  128   a ,  130   a  and  132   a  has been successfully authenticated and may be provided with access to the content distribution server and its constituent components identified above. Upon successful authentication, the messaging server  110  passes the identity of the user to the profile component  116 , which retrieves the user&#39;s profile  108  from the profile data  106  store for transmission to the messaging component  110 . The messaging component  110  may also provide the TV application  112  with a copy of the user&#39;s profile  108 , or the TV application component  112  may obtain a copy of the user&#39;s profile  108  directly from the profile component  116 . 
     The content distribution server  102  maintains a user profile  108  for each user in a profile data store  106 , which is managed by a profile component  116 . Alternatively, or in conjunction with the foregoing, a user profile may be stored on a remote server (not pictured), coupled to the content distribution server  102 . A user profile maintained on a remote server may be utilized by a plurality of servers coupled to the remote server, including the content distribution server  102 , to identify a given user and the user&#39;s activities. As indicated above, a user profile  108  maintains authentication information for the user, such as a username and password. The user profile may also be used by the messaging component  110  and TV application component  112  for the recordation of user interaction with the components,  110  and  112 , respectively. Accordingly, the user profile may maintain an historical record of the interactions of the user with the content distribution server  102 . 
     Those of skill in the art should understand, however, that a subset of this historical interaction may be written to the user profile  108 . For example, when the user is using the TV application component  112  to view TV content, the TV application component  112  sends a message to the profile component  116  to write indicia to the user&#39;s profile  108  in response to the receipt of a command, e.g., a change channel command. Similarly, when the messaging component  110  provides messaging content and related services to the user, the messaging component  110  sends a message to the profile component  116  instructing it to write indicia to the user&#39;s profile  108  in response to the receipt of a command, e.g., sending a message to another user or stepping into an on-line game. 
     The profile  108  also maintains a user&#39;s “context”. According to one embodiment, a user&#39;s context may be a notion of an action that a given user is performing at a given point in time, which may also include the location from which the user is performing that action. Put another way, a user&#39;s context may be what the user is doing at a given point in time, e.g., watching a given TV channel, playing an on-line game, listening to music, conducting an on-line transaction, etc. The context may also indicate from where or what type of device the client is connecting to the content distribution server  102 , e.g., a set top box  126   a  and  128   a , a personal computer  130   a , a mobile device  132   a , etc. By providing the user&#39;s context to the messaging component  110  and the TV application component  112 , each component,  110  and  112 , is capable of identifying and retrieving the proper content to provide the user with messaging content and related services unified with TV content and related services as is explained in greater detail herein. The profile component  116  receives updates to the given user&#39;s context form the messaging component  110  and TV application component  112  that the profile component  116  writes to the user profile  108  for the given user. The profile  108  for a given user therefore maintains an historical record of the user&#39;s context over a period of time. 
     The profile may also maintain information regarding other users of the system to whom a given user is related. For example, the given user may use a messaging client  126   c ,  128   c ,  130   c  and  132   c  on a client device  126   a ,  128   a ,  130   a  and  130   a  to identify one or more buddies, the identities of which are written to the given user&#39;s profile  108 . By traversing groups of related users, the profile component  116  is operative to identify social networks of users. Communities of users may also exist whereby an indication of the membership in a community is written to the given user&#39;s profile  108 . Similarly, the profile component  116  may identify subsets of a given user&#39;s buddies from the given user&#39;s total set of buddies. According to one embodiment, the profile component  116  calculates a social network for a given user that comprises all users with an N-degree relationship to the given user. For example, User A maintains a direct relationship with User B, and User B maintains a direct relationship to user C. User A and User C are related by two degrees, whereas each is related to User B by one degree. 
     The TV application component  112  identifies the user&#39;s context and retrieves the proper TV content for transmission over the network  100  to the client device  126   a ,  128   a ,  130   a  and  132   a  with which the user is interacting. Furthermore, the TV application component  112  may retrieve ancillary TV content including, but not limited to, audio, video, text, images and combinations thereof. According to one embodiment of the invention, the TV application component  112  retrieves TV content and ancillary TV content from a local content data store  114   a , which may aggregate TV content and ancillary TV content from a variety of disparate sources. Alternatively, or in conjunction, the TV application component  112  receives TV content and ancillary TV content from a local content data store  114   a , as well as over the network  100  from a remote content data store  114   b , where required content resides remotely from the server  102 . Similarly, the TV application component  112  may collect TV content from a plurality of TV content distribution systems (not pictured) for storage in the local and remote content data stores,  114   a  and  114   b , respectively. The TV application component  112  may selectively transmit TV content to users on the basis of a schedule for the transmission of TV content promulgated by the TV content distribution system for the region in which a given user is located. 
     The messaging component  110  is also provided with the user&#39;s context, thereby allowing the messaging component  110  to know what actions the user is performing, e.g., watching TV content, viewing ancillary TV content, playing an on-line game, listening to music, etc. Because the messaging component  110  is aware of the user&#39;s identity, the messaging component  110  may identify other users in the given user&#39;s social network, also referred to as the user&#39;s “buddies”. With knowledge of the given user&#39;s identity and other users in the given user&#39;s social network, the messaging component  110  may instruct the TV application  112  to propagate the given user&#39;s context to other users in the given user&#39;s social network. Propagating the user&#39;s context may include generating an image representing the user&#39;s context, which may further include other data describing the user&#39;s context (e.g., text, audio, video, combinations thereof, etc.). Alternatively, information regarding the user&#39;s context may be used to lookup and retrieve additional related information from a content data store  114   a  and  114   b . The TV application server  112  presents other users in the given user&#39;s social network with the given user&#39;s context, such as through the presentation of an icon. The TV application server  112  may provide a given user with the context of other users in the given user&#39;s social network, and vice versa. 
     The following example may be illustrative and is not intended to be limiting. Assume that the user is watching the TV program “The Apprentice” on channel three. According to one embodiment, the messaging component  110  identifies the user&#39;s buddies and instructs the TV application component  112  to propagate the user&#39;s context to his or her buddies. The TV application component  112  generates a thumbnail image representing the program “The Apprentice”, which the TV application component  112  propagates to the given user&#39;s buddies. The thumbnail is presented on a client device for a given buddy with information describing the program, e.g., the title and the fact that the user is watching the program on channel three. The TV application server  112  may modify information regarding the given user&#39;s content, e.g., scaling down the thumbnail image, on the basis of a given destination client device  126   a ,  128   a ,  130   a  and  132   a.    
     The messenger component  110  and TV application component  112  allow for a number of advanced features not available in content distribution systems known to those of skill in the art. Because the messaging component is aware of a given user&#39;s context and may receive input from a given client device  126   a ,  128   a ,  130   a  and  132   a , users of the content distribution server  102  may interact with one another. The messaging component  110  provides a given user&#39;s context to the TV application component  112 , which propagates the context to other users in the given user&#39;s social network and vice versa. The given user may select an indication of the context of other users in the given user&#39;s social network to initiate an action. Initiating an action may include starting an instant message conversation with the selected user, switching context to the context of the selected user, etc. Selections are passed to the messaging component  110 , which performs the requested action and provides content for the TV application component to consume and propagate as is appropriate to other users. One illustrative use of this functionality is shared viewing of content between a plurality of users, shared remote control functionality between a plurality of users, combinations thereof, shared remote and shared viewing with instant messaging between a plurality of users, etc. 
     The messaging component  110  also provides access to other application components  122 . Alternatively, other application components  122  may communicate directly with the TV application component  112  to provide content for distribution to one or more client devices  126   a ,  128   a ,  130   a  and  132   a  in communication with the content distribution server  102  over the network  100 . One exemplary other application component  122  is an on-line poker playing application. The other application  122  handles the main program logic for on-line poker playing game. Each user&#39;s context (which may comprise location information (e.g., playing on-line poker), the identities of other players in the game, what the given user&#39;s action is (hit, hold, double down), etc.) is provided to the messaging component  110 , which passes information regarding a given user&#39;s context to the TV application component for propagation to other players in the game. 
     Propagation of information regarding a given user&#39;s context may also be propagated to other users in a given user&#39;s social network who are not necessarily playing the on-line poker game. Those of skill in the art should recognize that other application components falling within the scope of the present invention are not limited to on-line poker playing components, and may include other applications that the messaging component  110  can interface with, including, but not limited to, music engines whereby the messaging component  110  may instruct the TV application component  112  as to the current song to which a user is listening, search applications whereby the messaging component  110  may instruct the TV application component  112  as to the keywords over which a user is searching and the related result set, etc. These are examples of a given user&#39;s context that the TV application component  112 , in conjunction with the messaging component  110 , may propagate to users of the content distribution server  102  to provide for a shared content consumption experience. 
     As indicated above, the TV application component  112  may propagate a given user&#39;s context to other users in the given user&#39;s social network, which may include channel information regarding a TV program that the given user is viewing. An issue arises, however, when individual users are accessing TV content in different time zones and locations with different channel assignments. The content distribution server  102  includes an electronic program guide component  118  communicatively coupled to the network  100  and operative to receive electronic program guide information, e.g., the program schedule for a given location and time zone. The electronic program guide component  118  queries program guide servers (not pictured) that are in communication over the network  100 , such as the program guide servers operated by Tribune Media Services. The electronic program guide component  118  stores the one or more electronic program guides in an EPG data store  120 . According to one embodiment of the invention, the EPG data store  120  is a relational database, but may be substituted by a tab delimited data store, a comma delimited data store, an object oriented database, a hybrid object-relational database, or other data stores known to those of skill in the art. Systems and methods for generating electronic program guides include U.S. Pat. No. 6,813,774, entitled “PROGRAM GUIDE DISPLAY APPARATUS AND PROGRAM GUIDE DISPLAY METHOD”, U.S. Pat. No. 6,763,522, entitled “SYSTEM AND METHOD FOR A DIGITAL TELEVISION ELECTRONIC PROGRAM GUIDE” and U.S. Pat. No. 6,611,958, entitled “ELECTRONIC PROGRAM GUIDE FEATURE FOR AV SYSTEM”, the disclosures of which are hereby incorporated by reference in their entirety. Furthermore, those of skill in the art recognize a number of electronic program guides are commercially available, including those available from Pioneer, Scientific Atlanta, Motorola, Gemstar/TVGuide (“GTVG”), Charter Communications, etc. 
     When the TV application component  112  propagates a given user&#39;s context to other users in the given user&#39;s social network, the TV application component  112  may query the electronic program guide component  118  to determine a local context for a user in the social network that corresponds to the user&#39;s context. For example, where the user is viewing a program on the ABC network, that same program is not necessarily being transmitted on the same channel in all locations and time zones, if the program is being transmitted at all. Accordingly, for each user in a given user&#39;s social network to which the TV application component  112  is to transmit a given user&#39;s context, the electronic program guide component  118  retrieves the electronic program guide from the EPG data store  120  for a user in the social network. 
     The electronic program guide component  118  executes a search in an attempt to locate the program that the given user is viewing in the electronic program guide. If successful, the electronic program guide component  118  instructs the TV application component  112  as to the channel on which the user in the social network may find the program that the given user is viewing being transmitted; the TV application component  112  may propagate this information as part of the given user&#39;s context. Where the electronic program guide component  118  cannot locate the given user&#39;s context in the electronic program guide, e.g., the program that the given user is viewing is not presently being transmitted in the time zone in which the user in the social network is located, the electronic program guide component  118  may identify alternate times at which the program is being transmitted, which the TV application component  112  may also propagate as part of the given user&#39;s context. The TV application component  112  transmits this information to the user in the social network. Where the client device  126   a ,  128   a ,  130   a  and  132   a  comprises digital video recording functionality (“DVR”), the TV application component  118  may provide the user in the social network with an opportunity to schedule recording of the program. Recording may also comprise the recording of content that is not selectable by a given user through interaction with an EPG, e.g., Internet based content. It should be noted that selection of a program or other content for recording may be recorded in the user&#39;s profile as a context or context change. 
     According to one embodiment of the invention, the content distribution server  102  uses a unique identifier to identify each program that it is transmitting to clients  126   a ,  128   a ,  130   a  and  132   a , e.g., stored in the EPG data store  120 . According to another embodiment of the invention, the content distribution server  102  utilizes unique program identifiers (“PID”) provided by an EPG data stream to identify each program that it is transmitting to clients  126   a ,  128   a ,  130   a  and  132   a . The electronic program guide component  118  searches the EPG data store  120  to locate the program that the given user is viewing and determines the program&#39;s unique identifier, which the TV application component  112  may propagate as part of the given user&#39;s context. A client device  126   a ,  128   a ,  130   a  and  132   a  that a user in the given user&#39;s social network is operating receives the given user&#39;s context and attempts to identify the program that the given user is viewing in a local electronic program guide, which may be stored on the client  126   a ,  128   a ,  130   a  and  132   a  or retrieved from a network source. 
     If successful, client side software, e.g., a TV client  126   b ,  128   b ,  130   b  and  132   b , instructs the user in the social network as to the channel on which he or she may find that program that the given user is viewing, which may include allowing the user in the social network to tune to channel on which the TV application component  118  is transmitting the program. Where the identifier for the program cannot be located in the local electronic program guide, client side software may identify alternate times at which the program is being transmitted. Where the client device  126   a ,  128   a ,  130   a  and  132   a  comprises digital video recording functionality (“DVR”), the client  126   a ,  128   a ,  130   a  and  132   a  may provide the user in the social network with an opportunity to schedule recording of the program. Recording functionality of the DVR may also include the recording of content that does not appear in an EPG, e.g., Internet based content. 
     As discussed above, interaction with the messaging component  110  and TV application component  112  may be recorded by the profile component  116 , which maintains a profile  108  for each user in a profile data store  106 . In other words, the profile  108  contains a history of the user&#39;s context changes as a function of time, allowing decisions to be made regarding the given user&#39;s preferences on this basis. For example, where the user&#39;s context is identified as viewing science fiction programs for long periods of time and news programs for short periods of time, a decision may be made that the user prefers science fiction programs. This may also account for sub-genres, e.g., science fiction/action, science fiction/horror, etc. Each profile  108  may also comprise context information as a function of time for other users in a given user&#39;s social network, as well as other users that utilize the content distribution server  102 . 
     A recommendation component  124  may utilize user profiles in the profile data store to supply recommended programming to the user, which may also include providing recommendations for using other applications, such as in response to on-line events, users with whom a given user might want to be a buddy, ancillary TV content, etc. According to embodiments of the invention, the recommendation component  124  may utilize a user profile in determining recommended content to a user. Alternatively, or in conjunction with the foregoing, the recommendation component  124  may also utilize the user profiles of a given user&#39;s buddies, e.g., the profiles of those users that are in the given user&#39;s social network. The recommendation component  124  may also compute a vector for the given user&#39;s profile and include those users with similar profile vectors in its calculation of recommended content. Also, the recommendation component  124  may utilize profiles for user communities, which contain aggregate context information for a community of users, when determining recommended content. Similarly, the recommendation component  124  may utilize a personalization service, such as My Yahoo!, which allows users to create and edit their own profiles for indicating media preferences (e.g., favorite channels or TV programs), which are stored on Yahoo! servers (which may be profile data stores  106 ) and made available to the recommendation component  124 . 
     The recommendation component  124  allows the content distribution server  102  to harness the viewing experience, habits and preferences of the users who are interacting with the content distribution server  102 . As indicated above, the recommendation component  124  may provide recommendations beyond TV content, extending to all services that the content distribution server offers. For example, a user may interact with the messaging component  110  to access other application components  122  through the TV application component  112 . One exemplary other application component  122  is an on-line poker game in which users play against each other on line. Where the user profile indicates that the user spends substantial time in the context of an on-line poker application  122 , the recommendation component may alert the user when an upcoming on-line poker tournament is approaching. 
     The system of the present invention illustrated at  FIG. 1  provides for a shared content consumption experience for users of the content distribution server  102 . A given user may be informed of the context of other users of the system, including users in the given user&#39;s social network. According to one embodiment, icons and accompanying textual data are propagated by the TV application component and presented to the given user on a client device  126   a ,  128   a ,  130   a  and  132   a , indicating the context of other users of the server  102 . The presentation of the context of other users in conjunction with the presentation of TV content allows for a shared viewing experience whereby a given user may know the context of other users and may change his or her context to that of another user. For example, where the context of a user in a given user&#39;s social network indicates the user in the social network is watching a program that is enjoyable to the given user, the given user may change his or her context to match that of the user in the social network (e.g., tuning to receive transmission of the same TV content that the user in the social network is consuming). Using the architecture described herein, a number of applications become available in the context of the TV consumption process, including, but not limited to personalization, community viewing, shared presence and context, messaging, access to ratings and recommendations (including community reviews), alerts, etc. 
     The content service provider  102  provides access to it functions and application components through the use of one or more application program interfaces (“API”)  100 . An API  100  is an interface, or set of calling conventions, by which a given application component accesses other application components and the services that the application components offer. By using the API  100 , a given application component advertises information regarding the functions and/or services that the given application component may provide to other components, which may also include the technique by which the functions or services are accessed. This allows the application components comprising the system to access supporting system and network services. For example, the API  100  allows client side applications to issue function calls for the performance of actions and accessing of services, such as tuning a channel, accessing an on-line game, listening to music, allowing the messenger component to interface with the TV application component or a messaging client to access EPG data, etc., as described herein. Although  FIG. 1  illustrates the API  100  as a separate system component, those of skill in the art recognize that each application component may provide an individual API  100  identifying the specific functions and services a given application component provides. Furthermore, application components, e.g., a messaging client  126   c ,  128   c ,  130   c ,  132   c , resident on client devices  126   a ,  128   a ,  130   a ,  132   a  may provide one or more APIs  100  advertising the functions and service the given application component provides. 
     One embodiment of a method for selecting content based upon the one or more users in a given user&#39;s social network (“buddies”) is illustrated in  FIG. 2 . According to the embodiment illustrated in  FIG. 2 , a user of a client device may initialize and connect to a content distribution system, step  205 , which may include a logon component. Initialization may comprise a client device powering up and initializing a communications stack, such as a TPC/IP stack, and opening a connection to the logon component over a network, e.g., the Internet. The logon component attempts to verify a user&#39;s credentials using information maintained in the user&#39;s profile that may be retrieved by a profile component, step  210 . 
     Television content is retrieved and displayed to a user on the user&#39;s client device, which may include the use of a TV application component, step  215 . According to one embodiment of the invention, a TV application component retrieves content from a content data store based upon a user&#39;s selection of content from among a plurality of television shows or listings for television shows displayed to the user. For example, an electronic programming guide component may retrieve electronic program guide data from an EPG data store identifying one or more items of television content available to a user. An electronic programming guide may be displayed to the user for selection of one or more items of television content from the electronic programming guide. According to another embodiment of the invention, the television content retrieved and displayed to a given user is based upon the user&#39;s profile maintained in a profile data store. For example, a user&#39;s profile may maintain information identifying the age, location, sex, etc., of the given user. Exemplary methods for retrieving content based upon a user profile are described in commonly owned U.S. patent application Ser. No. 10/752,819 entitled “SYSTEM AND METHOD FOR ACCESSING SPECIALIZED CONTENT ASSOCIATED WITH BROADCAST CONTENT,” the disclosure of which is hereby incorporated by reference in its entirety. A TV application component may retrieve and display content to a user based upon the one or more items of information maintained in the user&#39;s profile, according to methods further described herein. The content retrieved by a TV application component may comprise audio, video, text, images and combinations thereof. 
     A user&#39;s profile is further utilized to determine whether a given user has one or more buddies or whether the user is part of one or more social networks, step  220 . For example, a user may subscribe to one or more instant messaging services, such as Yahoo! Messenger. An instant messaging service may allow a user to designate and save buddies with whom the user may communicate by delivering instant messages via the respective instant messaging application. According to one embodiment of the invention, a user may designate, in a user profile, the one or more instant messaging services to which the user has subscribed. Similarly, a user may designate·one or more buddies with profiles maintained on the system described herein. A messaging component may retrieve the identity of a user&#39;s one or more buddies that maintain profiles on the system described herein and may also retrieve the identity of the one or more buddies identified in each respective instant messaging application identified in the user&#39;s profile. 
     A check is performed to determine whether a given user has one or more buddies designated in one or more instant messaging applications or whether the user has one or more buddies that maintain profiles on the system described herein, step  220 . If a user does have one or more buddies, a messaging component may retrieve the identity of the one or more buddies designated by the user in the one or more instant messaging applications or designated as buddies with profiles on the content distribution system, step  228 . The messaging component may further determine whether any of a given user&#39;s one or more buddies are currently active, step  229 . For example, a given buddy may be deemed active if the buddy has a profile and is currently logged in or accessing the content distribution system. Alternatively, or in conjunction with the foregoing, an inter-messaging component may be operative to communicate with one or more third party applications and the messaging component to identify whether a given buddy is logged into the third party application, which may include an instant messaging application. 
     If none of a user&#39;s one or more buddies are active, or if a user&#39;s profile does not identify one or more buddies, a profile component may be used to traverse the plurality of profiles maintained in a profile data store to select profiles of active users that match or are similar to the given user&#39;s profile, step  225 . The one or more active users&#39; profiles that match or are similar to the user&#39;s profile may be designated as the user&#39;s temporary buddies, step  225 . For example, a given user&#39;s profile may specify that the user is thirty years old, lives in New York City, is a football fan and enjoys watching reality television shows. A profile component may traverse a plurality of user profiles stored in a profile data store and retrieve one or more profiles for active users that identify interests or preferences similar to those of the given user, e.g., a match on one or more profile fields. The one or more active users selected (“users like you”) may be temporarily designated as the user&#39;s buddies. 
     After a user&#39;s buddies have been temporarily designated based upon the user&#39;s preferences and characteristics, step  225 , or designated according to information maintained in the user&#39;s profile, step  228 , the context of the user&#39;s one or more active buddies may be retrieved, step  230 , which may include retrieval by a messaging component. According to one embodiment of the invention, a context may be a notion of an action that a given user is performing at a given point in time, which may also include the location from which the user is performing that action. For example, a context may be what the user is doing at a given point in time, e.g., watching a given TV channel, playing an on-line game, listening to music, conducting an on-line transaction, etc. Additionally, the avatar associated with each respective buddy is retrieved, wherein an avatar may comprise an identifier for a given buddy, step  235 . For example, an avatar may comprise an image selected by a given buddy that identifies the given buddy. 
     The retrieved context of a user&#39;s one or more buddies may be displayed, along with each buddies&#39; respective avatar, on a client device for a given user in conjunction with TV content being viewed by the given user, step  240 . According to one embodiment of the invention, the context of a given user&#39;s one or more buddies is displayed as an image representing the context of a given buddy. For example, if a given buddy is viewing the television show “The Apprentice,” an image associated with the television show may be displayed on the given user&#39;s client device. Similarly, if a given buddy is playing in an online poker room, an image of a poker room associated with the given buddy&#39;s context may be displayed on the given user&#39;s client device. 
     According to another embodiment of the invention, the context of a given user&#39;s one or more buddies is displayed on the user&#39;s client device. For example, if a given user is viewing a television show and a buddy associated with the user is playing in an online poker game, the buddy&#39;s context may be displayed in conjunction with the TV content being viewed by the given user, whereby the user may view the buddy&#39;s poker game as it occurs. Similarly, if a buddy associated with the user is listening to music from a particular artist, an image associated with the musical artist as well as the musical audio content may be delivered to the user&#39;s client device allowing the user to listen to the music associated with the given buddy. According to one embodiment of the invention, a messaging component identifies the contexts of the buddies of a given user and requests one or more items of content from a TV application component or another application component based upon the one or more buddies&#39; identified contexts. The TV application component or another application component may retrieve content associated with the one or more buddies&#39; contexts from a content data store, which may include television content, context representations, musical content, etc. The content retrieved is delivered to the user&#39;s client device, allowing the user to view the contexts of the user&#39;s one or more buddies. 
     A user may select a representation of the context associated with each respective buddy that is retrieved and displayed on the user&#39;s client device. According to one embodiment of the invention, a messaging component may identify the context of a user&#39;s one or more buddies, and instruct a TV application component to deliver an image, icon, audio content, streaming data, etc., representing a buddy&#39;s context to the user&#39;s client device. Using a remote control device, a user may navigate to the visual or audio representation of a given buddy&#39;s context. According to one embodiment of the present invention, a user may select the representation of a given buddy&#39;s context to change the given user&#39;s context to the selected buddy&#39;s context. For example, if a given user is viewing the television show “The Apprentice” and a given buddy is viewing the television show “The Practice,” the user may select the representation of the buddy&#39;s context (viewing “The Apprentice”), which thereby causes the user&#39;s context to be changed to the buddy&#39;s context (viewing “The Practice”). 
     A check is performed to determine whether the user selected a representation of a given buddy&#39;s context, step  245 . If a user selects a representation of a given buddy&#39;s context the buddy&#39;s context is propagated to the user&#39;s client device, step  250 . According to one embodiment of the invention, a messaging component retrieves the context of the buddy selected and instructs a TV application component to retrieve and deliver the context of the buddy to the user&#39;s client device. If a user does not select the representation of a given buddy&#39;s context, the user&#39;s context remains unchanged, step  255 . The user may thereafter continue to review the content available to the user while also viewing the representations associated with the user&#39;s one or more buddies&#39; contexts. 
       FIG. 3  illustrates one embodiment of a method for retrieving and displaying the context of a given user&#39;s one or more buddies based upon the context of the given user. According to the method illustrated in  FIG. 3 , a user of a client device initializes and connects to a logon component, step  305 , to verify the user&#39;s credentials as maintained in the user&#39;s profile, which may be retrieved by a profile component from a profile data store, step  310 . A user may select from among a plurality of content available to the given user. For example, an electronic program guide component may search an EPG data store, operative to store one or more program guides, and display the one or more items of content available to a given user. A given item of content selected by a user may be retrieved from a TV application component and displayed on a given user&#39;s client device, step  315 . The content retrieved by a TV application component may be retrieved from a content data store and may comprise a TV show, movie, broadcast data, video on demand (“VOD”), etc. 
     The context selected by a given user may be retrieved and delivered to a messaging component in order to identify one or more buddies associated with the given user&#39;s context. For example, a given user may select a television show displaying a football game between the New York Giants and the Cleveland Browns from an electronic program guide, which may be displayed on the user&#39;s client device. Additionally, the user&#39;s profile may be retrieved and used to determine whether the given user has one or more buddies associated with the context selected. Similarly, a given user may select a VOD horror movie, which may be displayed on the user&#39;s client device. The user&#39;s profile may be retrieved and used to determine whether the given user has one or more buddies associated with the context selected by the user, which may comprise a movie genre. According to one embodiment of the invention, a buddy may be an individual associated with a given user in one or more instant messaging applications to which the given user has subscribed, which may include an indication in a user profile. According to another embodiment of the invention, a buddy comprises an individual with a profile maintained on the content distribution system indicating interests or characteristics that match or are otherwise similar to those of a given user. 
     A check is performed to determine whether a user has one or more buddies, which may be identified in the user&#39;s profile, step  320 . If the check performed at step  320  evaluates to true, an additional check is performed to determine whether a given user has one or more buddies or buddy lists associated with the context selected by the given user (e.g., context specific buddy), step  325 . According to one embodiment of the invention, a context specific buddy may be a buddy associated with a user&#39;s particular context. For example, a given user may be an avid football fan and designate one or more buddies, who are also interested in football, as football buddies. According to another embodiment of the invention, a user may identify multiple buddy lists, wherein each buddy list may comprise one or more buddies associated with a given context. The one or more buddy lists may be maintained on the content distribution system or on a remote server coupled to the content distribution system. If a user does not have one or more context specific buddies or context specific buddy lists, step  325 , the contexts of a user&#39;s default buddies may be displayed, wherein default buddies may comprise the one or more buddies not associated with any specific context, step  330 . 
     If a user does not have one or more buddies, step  320 , a profile component may traverse one or more profiles maintained in a profile data store to select one or more profiles of active users that are similar or match the profile for the given user, step  340 . According to one embodiment of the invention, the profile component traverses a plurality of user profiles stored in a profile data store to identify one or more profiles that that identify interests or preferences similar to those of the given user, e.g., a match on one or more profile fields. The one or more profiles of active users retrieved from a profile data store that are similar or match a given user&#39;s profile may be temporarily designated as given user&#39;s buddies. Alternatively, or in conjunction with the foregoing, the profiles retrieved may be further selected based upon the given user&#39;s context, thus constituting context specific buddies. 
     A check is performed to determine whether a given user&#39;s one or more context specific buddies are active, step  335 . If a given user&#39;s context specific buddies are not active, the user&#39;s one or more default buddies may be displayed, wherein a user&#39;s default buddies may comprise the user&#39;s one or more buddies not associated with any specific context, step  330 . According to one embodiment of the invention, a given buddy is active if the buddy has logged into the content distribution system. If one or more a given user&#39;s context specific buddies are active, or after a user&#39;s one or more context specific buddies have been temporarily designated based upon the user&#39;s profile or context, the contexts of the one or more context specific buddies are retrieved, step  345 , and displayed on the user&#39;s client device, step  350 . According to one embodiment of the invention, an audio or visual representation of the contexts of a user&#39;s one or more buddies are displayed on the given user&#39;s client device. A user may interact with the one or more buddies displayed, such as through the use of an instant messaging or chat session. 
       FIG. 4  illustrates one embodiment of a method for providing a user with control of the context of the user&#39;s one or more buddies. A user of a client device initializes and connects to a logon component, step  410 , to verify the user&#39;s credentials as maintained in a user profile, which may be retrieved from a profile data store, step  415 . A TV application component may provide content to the user for viewing on a client device, step  420 . According to one embodiment of the invention, content is selected by a given user from a plurality of content displayed to a user, such as through an electronic program guide. According to another embodiment of the invention, content is retrieved based upon one or more characteristics in a user&#39;s profile, according to methods described herein. 
     A user&#39;s one or more active buddies are identified, step  425 . According to one embodiment of the invention, a user&#39;s one or more buddies comprise individuals designated as buddies in one or more instant messaging applications as indicated in the given user&#39;s profile. According to another embodiment of the invention, a user&#39;s one or more buddies comprise one or more users with profiles maintained on the content distribution system. The one or more active buddies identified may be displayed on the user&#39;s client device with an audio or visual representation of each buddy&#39;s respective context, step  428 . For example, an inter-messaging component operative to communicate with a third party instant messaging application may identify whether a given buddy is logged into the third party application. An audio or visual representation indicating the third party application that a given buddy is logged into may be displayed on the user&#39;s client device. Similarly, a messaging component may identify the one or more buddies logged into the content distribution system and retrieve the context of the one or more buddies for display on the user&#39;s client device. 
     A user may select one or more of the active buddies and deliver a shared remote control request to the one or more selected active buddies. A check is performed to determine whether the user selected one or more of the active buddies associated with the given user, step  430 . If one or more active buddies are not selected, a shared remote control request is not generated or delivered to the one or more active buddies, and a user may continue to view the content displayed on the user&#39;s client device, step  420 . If one or more active buddies are selected, step  430 , a shared remote control request is delivered to the one or more active buddies selected, step  435 . According to one embodiment of the invention, a shared remote control request comprises a request to allow a given user to control the one or more content items displayed on a given buddy&#39;s client device. For example, a client device may be operative to display a plurality of items, such as one or more television shows, an online poker game, instant messaging applications, etc. A shared remote control request that is accepted by a given buddy may allow the given user to control content that is displayed on the given buddy&#39;s client device. 
     A check is performed to determine whether one or more buddies associated with the user accepted the shared remote control request, step  445 . If none of the selected buddies accepted the user&#39;s shared remote control request, the user does not gain control over the content displayed on the one or more selected active buddies&#39; client devices. If one or more selected buddies accept the shared remote control request, step  445 , the context of the user from which the shared remote control request originated is displayed on the one or more selected active buddies&#39; client devices, step  440 . For example, a user may be viewing the television show “Law and Order” and active buddies B1 and B2 associated with the user may be viewing the television shows “The Bachelor” and “The Practice,” respectively. The user may select active buddies B1 and B2 and deliver a shared remote control request to both buddies. B1 and B2 may either reject or accept the shared remote control request. If both B1 and B2 accept the shared remote control request, B1&#39;s client device and B2&#39;s client device are updated to reflect the context of the given user. Similarly, if B1 accepts the shared remote control request and B2 rejects the shared remote control notification, B1&#39;s client device is updated to reflect the user&#39;s context, whereas B2&#39;s client device is not be updated. A check is periodically performed to determine whether the user&#39;s context has changed, such as where the user changes the television channel tuned to on his or her client device, step  450 . If a user&#39;s context is not changed, no updates are made to the one or more active buddies that accepted the shared remote control request delivered by the user, step  440 . Where a given user&#39;s context changes, the change is propagated to the one or more active buddies that accepted the shared remote control request delivered by the user, step  455 , and the new context is displayed, step  440 . 
     According to one embodiment of the invention, Infrared (“IR”) signals are transmitted via a user&#39;s remote control to the user&#39;s set top box. A client application program interface may capture the IR signals and deliver the signals, via a client messenger application, to the content distribution system. The signals received by the content distribution system may be delivered to a messaging component, which may identify the one or more buddies that accepted the shared remote control request. The messenger component may propagate the signal to the set top boxes of the buddies that accepted the shared remote control request to reflect the user&#39;s context. Those of skill in the art recognize other methods for delivering a signal reflecting a user&#39;s context to one or more set top boxes. 
       FIG. 5  illustrates one embodiment of a method for facilitating community viewing and interaction in a given context. A user of a client device initializes and connects to a logon component, step  505 , which may include verifying the user&#39;s credentials as maintained in the user&#39;s profile, step  510 . Upon verifying a user&#39;s credentials, a check is performed to determine whether the given user has one or more buddies, step  515 , which may include accessing a user profile. According to one embodiment of the invention, a user&#39;s one or more buddies may be identified based upon the one or more instant messaging applications to which the given user has subscribed, which may be indicated in the user&#39;s profile. According to another embodiment, a user&#39;s buddies may comprise individuals with profiles maintained on the content distribution system. 
     If the user profile retrieved does not identify one or more buddies for the given user, a search is performed for “users like you,” step  525 . According to one embodiment of the invention, “users like you” comprise other users with profiles maintained on the content distribution system that match or are similar to a given user&#39;s profile with respect to characteristics identified in the user&#39;s profile including demographics, frequently viewed content, etc. For example, if a user&#39;s profiles identifies that the user is located in Houston, Tex., is forty-two years old and enjoys horror movies, profiles with similar age, preferences, location, etc., characteristics may be retrieved. The one or more profiles retrieved constituting “users like you” may be designated as a user&#39;s temporary buddies, step  525 . 
     Where a user&#39;s profile identifies one or more buddies, or after one or more profiles are retrieved constituting a match with the given user&#39;s profile and designated as temporary buddies, a check is performed to determine whether any of the user&#39;s one or more buddies are logged in to the content distribution system, step  520 . If none of a user&#39;s buddies are logged on to the content distribution system, the user is notified of such, step  530 . The user&#39;s one or more buddies may be monitored to determine whether any of the user&#39;s one or more buddies become active. 
     If one or more of a user&#39;s buddies are identified as active, step  520 , the user may deliver a synchronization request to the one or more user&#39;s buddies, step  535 . According to one embodiment of the invention, a synchronization request comprises an invitation delivered to one or more users to engage in community viewing. For example, the synchronization of a given user with one or more buddies may result in the user and one or more buddies engaging in a “movie theater” type viewing environment, wherein the user and one or more buddies view the same television show, movie, etc., at the same time while engaging in instant messaging or chat sessions. 
     The synchronization request delivered by a given user may be rejected or accepted by the user&#39;s one or more buddies, step  555 , which may be a subset of the user&#39;s active buddies. If the synchronization request is rejected by selected buddies associated with a given user, the user is notified of such, step  550 . The user&#39;s one or more buddies, or a subset of the user&#39;s buddies, may thereafter be monitored to determine whether any additional buddies associated with the user logon to the content distribution system, step  545 . A check is periodically performed to determine whether one or more additional buddies have logged on to the system described herein, step  540 . If one or more additional buddies associated with the given user logon to the content distribution system, the synchronization request may delivered to such buddies, step  535 . 
     If the synchronization request is accepted by selected buddies associated with the given user, the profiles of the one or more buddies are retrieved, step  560 . According to one embodiment of the invention, the profiles of the one or more buddies are used to identify the location of the one or more buddies as well as the content available to each respective buddy. For example, a user&#39;s one or more buddies may be located in various locations throughout the United States, the world, etc. Because of time zone differences, programming differences, etc., content available to a given user may not be available to a given buddy at the same time, on the same channel, etc. A user&#39;s profile may be used to identify the location of the user and the content available to the user. Similarly, the profiles of a user&#39;s one or more buddies may be used to identify the content available to each respective buddy. 
     According to one embodiment of the invention, the profiles retrieved for the user and the one or more buddies may be used by an electronic program guide component to identify content maintained in a content data store that is available to the user and the one or more synchronized buddies. For example, a given user&#39;s profile may indicate that the user is located in New York City, and a given buddy&#39;s profile may indicate that the buddy is located in San Francisco. Because of time zone differences, content available to the buddy located in San Francisco may not be available to the user located in New York City until hours later. Using the profiles associated with the user and the buddy, the electronic programming guide component may identify content, maintained in a content data store, which is available simultaneously to both individuals. According to another embodiment of the invention, the profiles retrieved for the user and the one or more buddies may be used to identify content maintained on the user&#39;s or one or more buddies&#39; client devices. For example, the user&#39;s and one or more buddies&#39; client devices may be operative to record content, such as a client device with digital video recording (“DVR”) functionality. The profiles for the user and one or more buddies may be used to identify content that is maintained on such devices. 
     The content available to the user and the user&#39;s one or more synchronized buddies may be displayed to the user and one or more synchronized buddies, step  562 . The user and one or more synchronized buddies may select a given item of content using a variety of methods. For example, a voting scheme may be used whereby the user and each synchronized buddy votes for the item of content they wish to view. The item of content receiving the greatest number of votes may be selected for display to the user and one or more synchronized buddies. Similarly, control may be granted to the user or a given synchronized buddy, who may select the item of content that is to be viewed by the user and the one or more synchronized buddies. Those of skill in the art recognize other techniques for selecting an item of content available to a plurality of users. 
     The user and one or more buddies may thereafter synchronize the starting time for the item of content selected, step  563 , wherein a starting time may comprise when a given item of television content is to be delivered to the user&#39;s and one or more buddies&#39; client devices. According to one embodiment of the invention, a messaging component is operative to select a start time that is N minutes after an item of content has been selected by the user and one or more synchronized buddies. The messaging component may instruct a TV application component to deliver the content selected to the user&#39;s and one or more buddies&#39; client devices at the start time selected. According to another embodiment of the invention, the user and one or more synchronized buddies may select a start time for the item of content selected. According to yet another embodiment of the invention, control may be granted to the user or one of the synchronized buddies, allowing the user or given synchronized buddy to select the start time for the item of content selected. The start time selected may be delivered to the messaging component, which may be operative to instruct the TV application to deliver the item of content selected at the start time selected. 
     The item of content selected is displayed on each of the synchronized buddy&#39;s client devices as well as the user&#39;s client device at the synchronized start time, step  565 . The user and the one or more synchronized buddies are thus able to simultaneously view the same item of content in a variety of locations on a plurality of client devices. According to one embodiment of the invention, additional services may be provided to the user and one or more synchronized buddies for communication. For example, an instant messaging application may be displayed in conjunction with the item of content selected, allowing the user and one or more synchronized buddies to engage in an instant messaging or chat session during display of the selected content item. Those of skill in the art recognize other applications that may allow for communication or interaction among a plurality of viewers in a community-viewing environment. 
       FIG. 6A  illustrates one embodiment of a method for facilitating the tagging and delivery of one or more content items to one or more buddies associated with a given user. A user of a client device initializes and connects to a logon component, step  605 , to verify the user&#39;s credentials as maintained in the user&#39;s profile, which may be retrieved from a profile data store, step  610 . Content is retrieved and delivered to the user&#39;s client device, step  615 , which may include the receipt of television content. According to one embodiment of the invention, a user may select the content retrieved and delivered to the user&#39;s client device using an electronic programming guide. For example, an electronic program guide component may search an EPG data store, which may be operative to store one or more program guides, and display the one or more items of content available to a given user. A given item of content selected by a user may be retrieved from a TV application component and displayed on a given user&#39;s client device, step  615 . 
     According to the embodiment illustrated in  FIG. 6A , a user viewing content on a given client device may tag, or otherwise mark an item or portion of an item of content for delivery to one or more buddies associated with the user. A tag may comprise “start” and “stop” delimiters, identifying a portion of content that a user wishes to deliver to one or more buddies associated with the user. For example, a user viewing a television show or movie may enjoy a particular scene and may wish to share the scene with one or more buddies. A user may thus tag the desired item of the television show, using start and stop tags, and deliver the tagged scene to one or more buddies. According to one embodiment of the invention, a given item of content that is tagged may be recorded to a user&#39;s client device. For example, a user of a client device with digital recording functionality (“DVR”) may locally record the content identified by the start and stop tags. According to another embodiment of the invention, tags may comprise identifiers that may be used to provide direct access to the tagged item of content. For example, a user may wish to tag a ten second scene in a two-hour movie. A start tag may identify the hour, minutes, and seconds where the scene beings, and a stop tag may identify the hour, minutes and seconds where the scene ends. The start and stop tags may be delivered to one or more buddies, providing the one or more buddies with direct access to the tagged item of content. 
     As content is displayed on a given user&#39;s client device, a check is periodically performed to determine whether the user has elected to tag the content being displayed, step  620 . If a user does not enter any tagging information, content continues to be displayed on the client device, step  615 , and the user may continue to select content from among the plurality of content available to the user. If a user enters a tag, the tag marked by the user is saved, step  625 . According to one embodiment of the invention, the content tagged by the user is saved locally on the user&#39;s client device or remotely on another device operative to record content. For example, a client device with digital video recording functionality (“DVR”) may provide the user with the ability to locally record a given item of tagged content. Alternatively, the tagged content may be recorded and stored in a remote content store operative to store one or more items of content. According to another embodiment of the invention, the content tagged by a user may be identified with start and stop identifiers. For example, start and stop identifiers may be stored and delivered to one or more buddies so as to provide a user&#39;s one or more buddies with direct access to the tagged item of a given television show, movie, etc. According to yet another embodiment invention, the content tagged by a user may be identified with offsets or pointers identifying a location in a given item of digital content. For example, a given offset or pointer may be delivered to one or more buddies identifying a location in an item of digital content. A given buddy may select the offset or pointer, thereby gaining direct access to the location in the item of content specified by the user. 
     A check is performed to determine whether a user has one or more buddies, step  630 . If a user&#39;s profile does not identify one or more buddies for the given user, processing ends, step  645 . The one or more tags saved locally on a user&#39;s client device or saved remotely on a device operative to store one or more tags may be later retrieved and viewed by the given user. 
     If a user&#39;s profile identifies one or more buddies, step  630 , the one or more buddies may be retrieved, step  632 , and displayed to the given user on the user&#39;s client device with audio or visual context representations associated with each respective buddies&#39; context, step  635 . A user may select one or more of the buddies displayed in order to designate the buddies as intended recipients of the tagged item of content. For example, using a selection device such as a remote control or mouse, a user may select one or more audio or visual context representations associated with the user&#39;s one or more buddies&#39; contexts to identify the intended recipients of the tagged item of content. A check is performed to determine whether a user has selected one or more buddies, step  640 . If a user does not select any buddies, the tagged content is not delivered to any of the user&#39;s one or more buddies and a user may continue to select content from among the plurality of content available to the user, step  615 . The tagged content saved on the user&#39;s client device or remotely on a device operative to store one or more tags may later be retrieved and viewed by the given user. 
     If the user selects one or more buddies, a check is performed to determine whether any of the one or more selected buddies are active, step  650 . If one or more of the user&#39;s buddies are identified as active, the tagged content is delivered to the respective buddies and may be viewed or saved by each respective recipient, step  655 . For example, a messaging component operative to identify a user&#39;s one or more buddies may instruct a local or remote storage device to deliver the given item of tagged content to the user&#39;s one or more selected buddies. If none of the selected buddies are active, the tagged content may be annotated with delivery information identifying the one or more recipients that are to receive the tagged content, step  660 , and delivered when the one or more identified recipients becomes active. For example, a selected buddy may receive a notification of the tagged content upon logging on to the content distribution system. Similarly, an inter-messaging component, operative to communicate with one or more third party instant messaging applications, may determine when a selected buddy logs onto the third party application instant messaging application and may deliver the tagged content to the selected buddy. Thereafter, a user may continue to retrieve and view the plurality of content available to the user, step  615 , and identify additional tags for delivery to the user&#39;s one or more buddies. 
     While  FIG. 6A  illustrates a method for tagging one or more items of content and delivering tags and tagged content to one or more buddies associated with a given user, the content distribution system illustrated in  FIG. 1  may further be used to select an item of content in an electronic programming guide and deliver the selection to one or more buddies associated with a given user. According to one embodiment of the invention, an electronic program guide component may deliver an electronic programming guide to a given user&#39;s client device identifying the one or more items of content available to a given user. A user may select one or more of the items of content identified in the electronic programming guide in order to view, record, etc., the one or more items of content selected. For example, a user may select a given item of content to arrange a date and time for recording the item on the user&#39;s client device. Similarly, the user may choose to select an item of content in order to automatically tune the user&#39;s client device to the item of content selected when the item is available. 
     A given user&#39;s selections from an electronic programming guide may be delivered to one or more buddies associated with the given user. According to one embodiment of the invention, a messaging component operative to identify a user&#39;s one or more buddies delivers a notification to the user&#39;s one or more buddies. The notification notifies the one or more buddies of the one or more items of content selected by the user from the electronic programming guide. For example, a messaging component may deliver a notification to a user&#39;s one or more buddies indicating the one or more items of content that the user has selected from an electronic programming guide for recording. Similarly, the messaging component may deliver a notification to a user&#39;s one or more buddies indicating the one or more items of content that will be automatically delivered to the user&#39;s client device when available. 
       FIG. 6B  is a flow diagram illustrating one embodiment of a method for facilitating web remote access of a user&#39;s set top box, digital video recorder (“DVR”) or other client device to control and interact with the content delivered to the user&#39;s one or more client devices. A user may remotely access the content distribution system via a client device (“remote access client device”) communicatively coupled to a web server operative to retrieve and display a logon page for the content distribution system. According to one embodiment of the invention, a remote access client device communicatively coupled to the Internet may access the content distribution system via a web browser that may display a logon web page for the content distribution system. 
     As illustrated in  FIG. 6B , a user may remotely logon to the content distribution system, step  665 , using a remote access client device coupled to a web server operative to retrieve and display a logon web page for the content distribution system. According to one embodiment of the invention, a user of a remote access client device initializes and connects to a logon component via the Internet to verify the user&#39;s credentials as maintained in the user&#39;s profile, which may be retrieved from a profile data store, step  668 . The profile retrieved for the given user may provide information on the one or more client devices associated with the user and coupled to the user&#39;s one or more set top boxes, step  670 . For example, a user may have previously registered one or more client devices associated with the user, such as digital video recorders (“DVR”) or high definition televisions that may be coupled to the user&#39;s one or more set top boxes. The functionality of the one or more client devices associated with the user and coupled to the user&#39;s one or more set top boxes may be identified in the user&#39;s profile or determined by the content distribution system. For example, the content distribution system may determine whether a given client device associated with the user and coupled to the user&#39;s one or more set top boxes is capable of recording items of content, displaying items of content in high-definition format, etc. 
     The profile retrieved for the user may be further used by the content distribution system to identify the content delivered to the user&#39;s one or more set top boxes. According to one embodiment of the invention, the content distribution system identifies the one or more electronic program guides available on a user&#39;s one or more set top boxes. The data from one or more electronic program guides stored and available on a user&#39;s one or more set top boxes may be displayed to the user on the user&#39;s remote access client device, step  675 . A user may select one or more items of content available to the user&#39;s one or more set top boxes as displayed in the one or more electronic program guides on the user&#39;s remote access client device. For example, using a selection device coupled to the remote access client device such as a keyboard or a mouse, a user may select one or more items of content from the one or more electronic program guides available to the user. 
     A check is performed to determine whether the user selected one or more items of content displayed on the user&#39;s remote access client device, step  680 . If a user does not select any items of content available to the user, the user may continue to browse the one or more items of content available, step  675 . When the user selects one or more items of content, step  680 , the user is presented with one or more options for interacting with the one or more items of content selected, step  681 . According to one embodiment of the invention, the one or more options available to the user are based upon the functionality of the user&#39;s one or more client devices, as identified in the user&#39;s profile. When the user selects an item of content from the one or more items of content displayed to the user via an electronic program guide on the remote access client device, the user may be presented with an option to record the item of content selected on the user&#39;s DVR. Similarly, a user&#39;s set top box may be further coupled to a high definition television. When the user selects an item of content, the user may be presented with an option to receive the item of content selected in non-high-definition format or in high-definition format. Further, a user may schedule a time for tuning the user&#39;s television to an item of content selected. Those of skill in the art recognize other options that may be available to a given user based upon the one or more client devices coupled to a user&#39;s one or more set top boxes, including recording an item of content, changing recording options, deleting a previously recorded item of content, selecting an item of content for automatic tuning, etc. 
     A check is thereafter performed to determine whether a user selected one or more of the options available to the user for the one or more items of content selected, step  682 . If a user does not select any of the one or more options available for the one or more items of content selected, the user may continue to browse the plurality of content available to the user, step  675 . When a user selects one or more of the of the options available for the one or more items of content selected, the user&#39;s selection is propagated to the user&#39;s one or more set top boxes, DVRs, or other client devices, step  684 . According to one embodiment of the invention, the user&#39;s selection is delivered by the content distribution system&#39;s messaging component to the one or more set top boxes associated with the given user. For example, a user may select the option to record an item of content available to the user at a particular time. The user&#39;s selection is delivered to the user&#39;s set top box or DVR, which then carries out the command to implement the selection. A user&#39;s profile may be annotated to reflect the one or more items of content selected by the user, step  685 , to provide the user with recommendations for items of content, according to methods described herein. 
       FIG. 7  is a flow diagram illustrating one embodiment of a method for facilitating the use of a client device for viewing television content and interacting with one or more other applications. A user of a client device initializes and connects to a logon component to verify the user&#39;s credentials, step  705 . Additionally, a user&#39;s profile is retrieved to identify the user&#39;s location, preferences, etc, step  710 . Content is retrieved and delivered to the user&#39;s client device, step  715 . According to one embodiment of the invention, a user may select the content retrieved and delivered to the user&#39;s client device using an electronic programming guide. For example, an electronic program guide component may search an EPG data store, operative to store one or more program guides for one or more locations and display the one or more items of content available to a given user. The one or more program guides retrieved may be retrieved based upon the location identified in the user&#39;s profile. A given item of content selected by a user may be retrieved from a TV application component and displayed on a given user&#39;s client device. 
     According to the embodiment illustrated in  FIG. 7 , a user may simultaneously view television content while engaging in a gaming application, with one or more buddies associated with the given user. For example, one or more games, such as gaming applications available on the Internet, may be displayed on the user&#39;s client device. A user may select the one or more gaming applications available in order to invoke the respective gaming application. 
     A check is performed to determine whether a user has selected one or more gaming applications, step  720 . If a user does not select a gaming application, television content continues to be displayed on the given user&#39;s client device, step  715 . A user may continue to select content from among the plurality of content available to the given user, as well as browse the one or more gaming applications available to the user. In contrast, if a user selects one or more gaming applications, step  720 , the one or more gaming applications may be executed and displayed on the user&#39;s client device, step  725 . According to one embodiment of the invention, the one or more gaming applications selected are delivered to a user&#39;s client device and locally executed. According to another embodiment of the invention, the one or more gaming applications selected are executed remotely and displayed on a given user&#39;s client device. The one or more gaming applications may be displayed in conjunction with the television content displayed on a given user&#39;s client device thus allowing the user to view television content as well as participate in the one or more gaming applications selected. 
     A check is performed to determine whether a user has one or more buddies, as identified in the user&#39;s profile, step  730 . The user&#39;s one or more buddies may be displayed to the user to permit the user to select one or more buddies to take part in the gaming application selected, step  730 . If a user has one or more buddies, the identity of the one or more buddies is retrieved, step  732 . Furthermore, the active buddies among the user&#39;s one or more buddies are identified and displayed to the user, step  734 . 
     If a user is not associated with one or more buddies, one or more profiles stored in a profile data store may be retrieved to identify other users with similar or matching interests, characteristics, etc., to those of the given user, step  740 . For example, a profile component may be operative to identify one or more profiles in a profile data store that identify user preferences that are similar to the current user. The one or more other users identified by a profile component may be designated as temporary buddies in order to allow the current user to engage in the gaming application selected. 
     A messaging component may deliver an invitation to the one or more active buddies identified by a user&#39;s profile or selected by a profile component to participate in the one or more gaming applications selected by the user, step  745 . A recipient of a gaming application invitation may either accept or reject the gaming invitation, step  748 . If none of the recipients of the user&#39;s gaming invitation accept the invitation, the user is notified of such, and may continue to view the television content being displayed, step  755 . The messaging component may pause for a given period of time, step  750 , and thereafter redeliver the one or more invitations to the user&#39;s one or more buddies, step  750 . If one or more the recipients of the user&#39;s gaming invitation accept the invitation, the context of the one or more buddies who accepted the invitation is retrieved, step  760 . 
     The context of the one or more buddies may be displayed on the user&#39;s client device, step  765 . For example, a user&#39;s client device may display an audio or visual representation of the one or more buddies&#39; contexts. Additionally, the gaming application selected by the user is propagated to each buddy who accepted the gaming invitation, step  768 . For example, if a user selects a poker gaming application and a given buddy is viewing a television show, upon accepting the gaming invitation, the buddy&#39;s client device may display both the television show and the gaming application. The user and one or more buddies who accepted the gaming invitation may thereafter engage in the gaming application selected. 
     It should be noted that while  FIG. 7  illustrates the use of a gaming application in conjunction with the viewing of television content, according to another embodiment of the invention, one or more other applications may be selected and executed in conjunction with television content, wherein other applications may comprise applications executable locally on a client device or remotely on a device operative to execute one or more applications for display on the client device. 
     The content distribution system illustrated in  FIG. 1  may further be used to provide users with the ability to enter ratings and receive recommendations for one or more items of content.  FIG. 8  is a flow diagram illustrating one embodiment of a method for entering a rating for a given item of content and delivering the rating to a user&#39;s one or more buddies. 
     During or after the display of an item of content, which may include television content, a user may be presented with an option to enter a rating for the given item of content, step  820 . According to one embodiment of the invention, a user is presented with a graphical user interface allowing the user to enter one or more ratings for a given item of content. A rating may comprise an indication of the user&#39;s opinion of the item of content. For example, a user may indicate whether the content was favorable using a “thumbs up” icon or unfavorable using a “thumbs down” icon. Similarly, a user may enter ratings for one or more categories or characteristics associated with the item of content. For example, if a user is viewing a horror film, the user may provide a rating for one or more of the actors, the level of scariness of the film, the suspense of the film, etc. Furthermore, a user may also enter rating information for other applications, including gaming applications, web sites, etc. For example, a user participating in an online gaming application may provide a rating indicating whether the game is challenging, whether the graphics are appealing, etc. Those of skill in the art recognize other types and characteristics of content that may be rated by a given user. 
     A user&#39;s profile may be annotated with the rating entered by the user for the given item of content to provide the user or the user&#39;s one or more buddies with recommendations for additional content, step  825 . A user&#39;s profile annotated with rating information may be used to determine content that the user may enjoy and alert the user when such content is available. For example, a recommendation component may inspect a user&#39;s profile annotated with a plurality of ratings to identify one or more items of television content that the user may enjoy based upon the user&#39;s previous ratings. A recommendation component may direct a TV application to retrieve one or more items of content from a content data store and deliver the items of content to a user&#39;s client device based upon the user&#39;s ratings. Similarly, a recommendation component may inspect a user&#39;s profile and instruct another application component, operative to store other applications, such as gaming applications, to deliver the respective applications to a user&#39;s client device based upon the user&#39;s ratings. 
     The user&#39;s rating may further be stored in a recommendation component operative to store one or more user ratings for items of content to allow the user&#39;s rating to be propagated to the user&#39;s one or more buddies or utilized to provide recommendations to additional users, step  830 . A check is performed to determine whether the user has one or more buddies as identified in the user&#39;s profile, step  835 . If a user does not have one or more buddies, processing ends, with storage of the user&#39;s rating, step  850 . If a user does have one or more buddies, an audio or visual representation of each buddy&#39;s context may be displayed on the user&#39;s client device to allow the user to select one or more of the buddies, step  840 . A check is performed to determine whether the user selected one or more buddies, step  845 . If a user does not select one or more buddies, processing ends. If one or more of the buddies are selected, each respective buddy selected may receive a notification of the user&#39;s rating for the given item of content, allowing the user&#39;s one or more buddies to base their selections of content on one or more buddies&#39; ratings, step  860 . For example, a buddy logged onto the content distribution system may receive an alert notifying the user of the rating. Similarly, a buddy not logged onto the content distribution may receive a notification upon logging onto the content distribution system notifying the buddy that a user has rated a given item of content. Alternatively, or in conjunction with the foregoing, a buddy may receive an alert via an email application, instant messaging application, etc., notifying the buddy of the user&#39;s rating for the given item of content. 
     The ratings entered by one or more users of the system described herein may be utilized to provide recommendations for one or more items of content.  FIG. 9  is a flow diagram illustrating one embodiment of a method for generating one or more recommendations based upon ratings entered by one or more users. According to the embodiment illustrated in  FIG. 9 , a user may logon to the content distribution system via a logon component, step  905 . A profile component may retrieve a user&#39;s profile from a profile data store to verify the user&#39;s credentials, step  910 . A user logged into the content distribution system may make a request for a recommendation for an item of content, wherein an item of content may comprise television content, gaming content, Internet content, etc. A check is performed to determine whether a user has requested a recommendation, step  915 . If a recommendation is not requested, the plurality of content available to the user may be displayed, allowing the user to select one or more items of content, step  925 . Where a user submits a request for a recommendation, a further check is performed to determine whether the user has provided ratings for at least N items of content associated with the recommendation sought, step  930 . According to one embodiment of the invention, a recommendation component inspects the user&#39;s profile to determine whether the user&#39;s profile is annotated with one or more ratings for the type of content selected. For example, if a user requests a recommendation for a mystery movie, a check is performed to determine whether the user has rated at least N mystery movies or television shows, wherein N may comprise a threshold. A recommendation component may inspect the user&#39;s profile to determine whether the user has rated at least N mystery movies or television shows. 
     If a user has rated at least N items of content associated with the type of content selected, the recommendation component may generate a recommendation based upon the user&#39;s one or more ratings, step  935 . For example, a profile annotated with three different ratings for mystery films may identify that the given user enjoys a particular actor and enjoys black and white films. The recommendation component may generate a recommendation based upon the user&#39;s previous ratings and deliver a request to a TV application component to retrieve one or more items of content from a content data store that match the user&#39;s preferences. A threshold may be used to increase the accuracy of the recommendation made by the recommendation component. For example, a profile with only one mystery movie rating may not provide enough information for the recommendation component to make an accurate recommendation. Therefore, a threshold may be used to increase the likelihood that the recommendation component calculates a recommendation that matches a given user&#39;s preferences. 
     If a user has not rated at least N items of content related to the type of recommendation requested, a check is performed to determine whether the given user has one or buddies, step  940 . According to one embodiment of the invention, a user&#39;s profile is used to determine the one or more buddies designated by the user. The profiles of one or more buddies identified in a given user&#39;s profile may be used to provide recommendations for one or more items of content. 
     According to the embodiment illustrated in  FIG. 9 , if a user&#39;s profile does not identify one or more buddies, a search is performed to identify users of the content distribution system with profiles identifying similar or matching preferences with those of the given user, step  945 . According to one embodiment of the invention, a profile component traverses the plurality of profiles that may be stored in a profile data store to identify users with preferences that match or are similar to those of the given user. For example, if a user&#39;s profile indicates that the user is sixty-eight years old, lives in Greenwich. Conn. and enjoys movies with the actor. Marlon Brando, one or more profiles with similar characteristics and preferences may be retrieved and designated as a user&#39;s temporary buddies in order to provide the user with one or more recommendations. 
     If a user&#39;s profile identifies one or more buddies, or after one or more temporary buddies have been designated for the user using one or more matching or similar profiles, a check is performed to determine whether any of the one or more buddies has rated at least N items of content related to the recommendation sought by the given user, step  950 . For example, if a user is seeking a recommendation for a gaming application, a check is performed to determine whether any of the one or more buddies has rated at least N gaming applications. If one or more of a user&#39;s buddies has rated at least N items of content associated with the type of content sought by the given user, a recommendation component may generate a recommendation based upon the one or more ratings from the user&#39;s one or more buddies, step  955 . For example, if a user is seeking a recommendation for a gaming application and a buddy associated with a user has rated eight gaming applications, the recommendation component may generate a recommendation based upon the gaming application that received the highest rating from the buddy. Similarly, if a user has a plurality of buddies and each buddy has rated a common gaming application, the recommendation component may calculate the average rating of the one or more gaming applications and recommend the gaming application with the highest rating to the user. Those of skill in the art recognize other methods for generating a recommendation based upon one or more buddy ratings. 
     According to the embodiment illustrated in  FIG. 9 , if none of a user&#39;s one or more buddies has rated at least N items of content associated with the item of content sought by the given user, a recommendation component may generate a recommendation based upon characteristics of the user as indicated in the user&#39;s profile, step  960 . For example, a user&#39;s profile may indicate that the user is twenty-three years old, lives in Arizona, attends Arizona State University and plays football. Therefore, a recommendation component may generate a recommendation for television channels broadcasting football games played by colleges located within Arizona. The recommendation component may instruct a TV application component to retrieve and deliver one or more items of content stored in a content data store associated with Arizona football games to the user&#39;s client device. Those of skill in the art recognize the plurality of content that may be retrieved based upon one or more user characteristics as identified in a user profile. Alternatively, or in conjunction with the foregoing, the recommendation component may provide the user with a recommendation based upon the popularity of one or more items of content. For example, the recommendation component may identify items of television content, audio content, gaming applications, etc., that are most often viewed, accessed, downloaded, etc., and notify the user of such items. The recommendation component may instruct the TV application component to retrieve and deliver one or more items of content stored in a content data store that are identified as being the most frequently selected, downloaded, accessed, etc. 
     The system of the present invention may also be used to alert a user of one or more events according to user characteristics and preferences identified in a user profile. A user may be interested in various events, warnings, announcements, etc. Current methods for delivering such information to a user may require a user to view a news broadcast, access a particular website, search for content, etc. In order to overcome shortcomings associated with current methods for delivering user specific information, the present invention provides systems and methods that facilitate the retrieval and delivery of various alerts based upon on or more user preferences. 
       FIG. 10  is a flow diagram illustrating one embodiment of a method for identifying one or more user alerts. One or more items of content are displayed on the user&#39;s client device, step  1015 , which may include television content. While logged into the content distribution system, a user may wish to enter one or more alerts to generate a notification of events that are of interest to the given user. For example, a user may wish to receive notification when a movie starring the actor Harrison Ford is broadcast. Similarly, a user who frequently travels may wish to receive notification of traffic reports for one or more highways. Further, a user may wish to receive notification about news events that are of interest to the user. Those of skill in the art recognize other information or events exist for which a given user may wish to receive one or more alerts. 
     A check is performed to determine whether a given user has entered one or more alerts, step  1020 . According to one embodiment of the invention, a user may enter one or more alerts using a graphical user interface that may be accessed by a user of a client device who is logged in to the system described herein. If a user enters an alert, the user&#39;s profile is annotated with information identifying the alert indicated by the user, step  1025 . If a user does not enter one or more alerts, the user&#39;s profile may be used to generate one or more alerts, step  1030 . Additionally, a user&#39;s profile may also be used to supplement the one or more alerts entered by the user, step  1030 . For example, a user&#39;s profile may indicate the user is ninety-five years old, lives in Miami, Fla. and enjoys viewing television shows associated with animals. A recommendation component may annotate a user&#39;s profile with one or more alerts based upon the user&#39;s preferences as identified in the user&#39;s profile. Thus, the abovementioned user&#39;s profile may be annotated with one or more alerts to provide the user with a notification of television shows that display animals, discounts offered to senior citizens in the Miami, Fla. area, etc. 
     A recommendation component may further annotate the user&#39;s profile with alerts based upon a user&#39;s one or more recommendations as identified in the user&#39;s profile. For example, a user&#39;s profile may indicate that a user enjoyed viewing several movies with the actor Al Pacino. Thus, the user&#39;s profile may be annotated with one or more alerts to notify the user when one or more items of content with the actor Al Pacino are available to the user. Those of skill in the art recognize other alerts that may be generated based upon information maintained in a user&#39;s profile. 
       FIG. 11  is a flow diagram illustrating one embodiment of a method for delivering an alert to a user based upon information maintained in a user profile. A TV application component may retrieve one or more items of content from a content data store to deliver to a user&#39;s client device, step  1115 , and the user&#39;s profile may be utilized to monitor the one or more alerts identified by the user or generated by a recommendation component, step  1120 . According to one embodiment of the invention, a messaging component is operative to monitor the one or more alerts associated with a given user&#39;s profile. The messaging component may periodically inspect one or more content data stores to identify information pertaining to a user&#39;s one or more alerts, step  1125 . If information associated with a user&#39;s one or more alerts is identified, the messaging component may instruct a TV application component to deliver a message or other notification to the user&#39;s client device, step  1130 . 
     A user presented with an alert may select the alert in order to retrieve additional information on the alert or to change the user&#39;s context to display information associated with the alert, step  1135 . For example, if a given alert notifies a user of a major traffic accident, the user may select the alert, which may change the user&#39;s context to a news broadcast detailing the events of the traffic accident. Similarly, if a given alert notifies a user of a movie that the user may enjoy, the user may select the alert to change the context to tune to the given movie. If information for a given alert is not located, or if a user does not select the alert displayed on the user&#39;s client device, the user&#39;s context is unchanged, and the one or more alerts identified in the user&#39;s profile continue to be monitored, step  1120 . 
     A user&#39;s one or more alerts and ratings may further be used to customize the delivery of one or more advertisements to the user&#39;s client device.  FIG. 12  is a flow diagram illustrating one embodiment of a method for delivering advertisements to a user, which may be based upon the user&#39;s one or more alerts and ratings. The user&#39;s profile is retrieved, step  1210 , and content is delivered to the user&#39;s client device, step  1215 . A check is performed to determine whether the user&#39;s profile contains one or more ratings or one or more alerts, step  1220 . If the user&#39;s profile contains one or more ratings or one or more alerts, advertisements related to the one or more ratings or one or more alerts may be retrieved,  1230 . For example, a content data store may store a plurality of advertisements for various products and services. A given user&#39;s profile may indicate that the user lives in Memphis, Tenn., enjoys classical music, is a soccer fan, etc. A recommendation component may instruct a TV application component or another application component to retrieve one or more advertisement related to classical music, soccer, etc., and deliver the advertisements to a user&#39;s client device. Similarly, a user&#39;s profile may indicate that the user wishes to receive weather related alerts. A recommendation component may instruct the TV application component or other application component to retrieve advertisements for weather related products and services and deliver such advertisement to the user&#39;s client device, step  1235 . 
     If a user&#39;s profile does not have one or more ratings or alerts, the user&#39;s current context may be retrieved by a messaging component and used to determine one or more advertisements to deliver to the user&#39;s client device, step  1225 . For example, a given user may be viewing the movie “The Shawshank Redemption.” The messaging component may retrieve the user&#39;s context, and based upon the context retrieved, instruct a TV application component to deliver one or more advertisement related to the user&#39;s context. The TV application may retrieve advertisements, such as the soundtrack to the movie “The Shawshank Redemption,” and deliver such advertisements to the user&#39;s client device, step  1235 . 
     A user may select one or more of the advertisements displayed on the user&#39;s client device, step  1240 . If a user selects a given advertisement, the user&#39;s context may be changed to display additional information on the product or service advertised, step  1245 . If a user does not select one or more of the advertisements displayed, the user context is unchanged, step  1215 . 
       FIG. 13  is a screen diagram illustrating content that may be delivered to a client device. A user of the system described herein may logon using a logon component that may verify the user&#39;s credentials as stored in a user profile. Once logged in, a user may select from among a plurality of content available to the user that may be delivered to a user&#39;s client device. As illustrated in  FIG. 13 , the content  1305  delivered to a client device may comprise television content that is available to a given user. According to one embodiment of the invention, content  1305  that is available to a user is identified based upon a user&#39;s location as indicated in the user&#39;s profile. For example, an electronic program guide component may query an electronic program guide data store to identify one or more electronic program guides available to a given user based upon the user&#39;s location as indicated in the user&#39;s profile. The one or more electronic program guides identified by the electronic program guide component may be displayed to the user on the user&#39;s client device. The user may select an item in the electronic program guide, which may result in a TV application component retrieving and delivering content  1305  to the user&#39;s client device. 
     While  FIG. 13  illustrates the retrieval and delivery of television content  1305  to a user&#39;s client device, other content may be retrieved and delivered to a given user&#39;s client device. According to one embodiment of the invention, a user may select one or more additional applications from another application component that may store other applications, such as gaming applications, instant messaging applications, etc. The content  1305  selected and displayed on a given user&#39;s client device may be modified based upon the type of destination client device. For example, content selected for delivery to a cellular phone device may be sized according to the size of the display of the cellular phone device. 
       FIG. 14  is a screen diagram illustrating an electronic program guide that may be used by a given user of a client device to select one or more items of television content. As illustrated in  FIG. 14 , the content  1405  selected and displayed in  FIG. 13  is minimized to allow a user to continue view the television content  1405  selected while browsing the plurality of content  1415  and  1410  available to the given user. 
     The electronic program guide  1400  displayed to a user of a client device may be retrieved by an electronic program guide component that may identify the one or more electronic program guides available to a given user. According to one embodiment of the invention, the content available  1415  and  1410  to a given user is identified based upon a user&#39;s location as identified in the user&#39;s profile. For example, an electronic program guide displayed to a user in San Francisco, Calif. may correspond to Pacific Standard Time, whereas an electronic program guide displayed to a user in New York City may correspond to Eastern Standard Time. According to another embodiment of the invention, the content available  1415  and  1410  to a given user may be identified based upon a user&#39;s preferences as identified in a user profile. For example, a user may subscribe to one or more paid movie services, offering the user additional content. An electronic program guide component may retrieve an electronic program guide  1400  corresponding to a user&#39;s subscription service. Those of skill in the art recognize other methods for retrieving and displaying an electronic program guide to a user of a client device. 
     A user may traverse the plurality of content  1415  and  1410  displayed in the electronic program guide  1400  using a selection device such a remote control and select one or more of the content items  1415  and  1410  available to the user. If a user selects a given item of content  1415  and  1410 , the content may be retrieved by a TV application component and displayed on the given user&#39;s client device. As illustrated in  FIG. 14 , the content selected may be modified in order to properly display the content in conjunction with the electronic program guide available to the given user. 
     In addition to selecting content displayed in an electronic program guide, a user may also select content associated with the user&#39;s one or more buddies as illustrated in  FIG. 15 . According to one embodiment of the invention, a user profile may be used to identify one or more buddies  1545 ,  1550 ,  1555 ,  1560  and  1565  designated by the user in one or more instant messaging applications. Similarly, a user profile may identify buddies that maintain profiles on the content distribution system. 
     A messaging component may be used to identify the one or more buddies identified in a given user&#39;s profile and retrieve the context associated with each buddy  1545 ,  1550 ,  1555 ,  1560  and  1565  who may be active. For example, an active buddy may comprise a buddy who has logged in and maintains a profile on the system described herein. A messaging component may instruct a TV application component to deliver the context associated with a given buddy  1545 ,  1550 ,  1555 ,  1560  and  1565  to a given user. For example, a TV application component may deliver content, such as a television show, to a given buddy&#39;s client device. When a user logs on to the system described herein, a user may request to view the content being viewed by the one or more buddies identified in the user&#39;s profile. A messaging component may identify the one or more buddies and each respective buddy&#39;s  1545 ,  1550 ,  1555 ,  1560  and  1565  context and instruct a TV application component to propagate the one or more buddies&#39; contexts to the given user. 
     According to the embodiment illustrated in  FIG. 15 , a TV application component generates a thumbnail  1520 ,  1525 ,  1530 ,  1535  and  1540  image representing the context of a given buddy  1545 ,  1550 ,  1555 ,  1560  and  1565 , which the TV application component propagates to the given user&#39;s client device. The thumbnail  1520 ,  1525 ,  1530 ,  1535  and  1540  may be annotated with information describing the particular context, e.g., title, channel, rating, etc. The context of a user&#39;s one or more buddies  1545 ,  1550 ,  1555 ,  1560  and  1565  may also be displayed in conjunction with the content  1505  being viewed by the given user. The display area of a given user&#39;s client device may be modified to accommodate for the user&#39;s one or more buddies  1545 ,  1550 ,  1555 ,  1560  and  1565  and the content  1505  being viewed by the user. 
     According to another embodiment of the invention, a TV application component delivers the actual content being viewed by a given buddy  1545 ,  1550 ,  1555 ,  1560  and  1565 . For example, a buddy  1545 ,  1550 ,  1555 ,  1560  and  1565  associated with a given viewer may be viewing the show “The Apprentice.” As described above, one method of indicating the buddy&#39;s  1545 ,  1550 ,  1555 ,  1560  and  1565  context is delivering a thumbnail image  1520 ,  1525 ,  1530 ,  1535  and  1540  associated with the buddy&#39;s  1545 ,  1550 ,  1555 ,  1560  and  1565  context to the user&#39;s client device. Additionally, the TV application may deliver streaming content to the user&#39;s client device, allowing the user to view the content of a given buddy  1545 ,  1550 ,  1555 ,  1560  and  1565  in conjunction with the content  1505  being viewed by the given user. While the screen diagram illustrated in  FIG. 15  provides the context of five buddies  1545 ,  1550 ,  1555 ,  1560  and  1565 , additional or fewer buddies may be displayed to a given user based upon a threshold or the number of buddies identified in a user&#39;s profile. 
     Advertisements or other ancillary content may also be displayed in conjunction with content and the context of a user&#39;s one or more buddies. As illustrated in  FIG. 15 , an advertisement  1510  is display that corresponds to the current content  1505  being displayed on the user&#39;s client device. The advertisement  1510  displayed may be selected, thereby allowing a user to acquire further information for the product or service advertised,  1510 . The one or more advertisements  1510  displayed in conjunction with content  1505  and a user&#39;s one or more buddies  1545 ,  1550 ,  1555 ,  1560  and  1565  may be selected according to a user&#39;s ratings or alerts, as described herein. Similarly, the one or more advertisements  1510  displayed on a user&#39;s client device may be selected based upon the content  1505  selected and delivered to the user&#39;s client device. For example, the advertisement  1510  displayed is an advertisement for a movie associated with the content  1505  displayed. 
       FIG. 16  is a screen diagram illustrating the plurality of buddies  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  associated with a user and a visual representation of each buddy&#39;s respective context. A user&#39;s one or more buddies, as identified in the user&#39;s profile, may view television content, participate in an online gaming application, watch a movie, etc. A visual representation of each buddy&#39;s respective context may be propagated to a user&#39;s client device via a TV application component in conjunction with television content selected by a given user. 
     Using a selection device, such as a remote control, keyboard, mouse, etc., a user may traverse the visual representation of the one or more buddies&#39;  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  contexts displayed on the user&#39;s client device. As illustrated in  FIG. 11 , as a user traverses the visual representations of the one or more buddies&#39;  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  contexts displayed, a particular visual representation of a buddy&#39;s  1615  context may be highlighted  1645  or otherwise marked. Information  1640  may be displayed to the user further identifying the context of the highlighted buddy, such as program, title, channel; network, rating, etc. As a user traverses the context associated with the user&#39;s one or more buddies  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635 , a user may continue to view and select content  1605 . For example, a user may simultaneously view the context of the user&#39;s one or more buddies  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  while changing television channels, engaging in an online gaming application, watching a movie, etc. 
     According to one embodiment of the invention, the display of a user&#39;s one or more buddies  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  and associated contexts may be turned on or off. For example, a user viewing a movie may wish to have the movie occupy the entire display area of the user&#39;s client device. The user may thus deactivate the display of the user&#39;s buddies  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  and associated contexts. Similarly, a user may limit the number of buddies  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  and associated contexts displayed on the user&#39;s client device. For example, a user&#39;s profile may identify twenty buddies who may all be active while the user is engaging in an online gaming application. The user may wish to limit the number of buddies  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  and associated contexts displayed in order to minimize clutter on the screen, maximize the display of the gaming application, etc. According to another embodiment of the invention, a user may modify the location of the display of buddies  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  and associated contexts in the display area of the user&#39;s client device. While the screen diagram illustrated in  FIG. 16  shows a row of buddies  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  with associated contexts on the bottom of the display area, one or more of the buddies  1610 ,  1615 ,  1620 ,  1625 ,  1630  and  1635  and associated contexts may be placed in positions that accommodate a user&#39;s needs or preferences. 
       FIG. 17  is a screen diagram illustrating another embodiment of the plurality of buddies  1710 ,  1715 ,  1720 ,  1725 ,  1730  and  1735  associated with a user and each buddy&#39;s respective context  1770 ,  1775 ,  1780 ,  1785 ,  1790  and  1795  that may be selected by the user. The context  1770 ,  1775 ,  1780 ,  1785 ,  1790  and  1795  of a user&#39;s one or more buddies  1710 ,  1715 ,  1720 ,  1725 ,  1730  and  1735 , as identified in the user&#39;s profile, may be propagated to a user&#39;s client device via a TV application component. A user&#39;s one or more buddies  1710 ,  1715 ,  1720 ,  1725 ,  1730  and  1735  may be viewing television content, engaging in an online gaming application, etc. The context  1770 ,  1775 ,  1780 ,  1785 ,  1790  and  1795  of each buddy  1710 ,  1715 ,  1720 ,  1725 ,  1730  and  1735  may be viewed on the user&#39;s client device in conjunction with the one or more items of content  1705  selected by the user. 
     As previously described, using a selection device, a user may traverse the contexts  1770 ,  1775 ,  1780 ,  1785 ,  1790  and  1795  associated with the user&#39;s one or more buddies  1710 ,  1715 ,  1720 ,  1725 ,  1730  and  1735 . When a given context  1780  associated with a buddy  1720  is highlighted or otherwise marked, additional information  1798  associated with the buddy&#39;s  1720  context  1780 , such as channel, title, network, etc., is displayed to the user. Additionally, if a user selects a context  1780  associated with a given buddy, a user may be presented with one or more options  1740 ,  1745  and  1750 . For example, the screen diagram illustrated in  FIG. 17  presents a user selecting a buddy&#39;s context  1780 , which is an online poker gaming application. When the user selects the context  1780  associated with the buddy  1720  participating in the online poker gaming application, the user is presented with a plurality of options. The “watch”  1745  option allows the user to view the poker game that the buddy is participating in. For example, by selecting “watch,”  1745  the buddy&#39;s context  1780 , namely the online poker gaming application, may be propagated to the user&#39;s client device. The user may continue to view the television content  1705  along with the buddy&#39;s online poker game. Selecting “cancel”  1750  may allow the user to continue traversing the one or more contexts  1770 ,  1775 ,  1780 ,  1785 ,  1790  and  1795  associated with the users one or more buddies  1710 ,  1715 ,  1720 ,  1725 ,  1730  and  1735 . 
     By selecting “play,”  1740  a user may elect to participate in the buddy&#39;s  1720  online poker gaming application. For example, if the user selects “Play,”  1740  the context  1780  of the buddy  1720  is propagated to the user&#39;s client device. Moreover, the user&#39;s profile may be used to identify the user as a participant and engage the user in the poker game.  FIG. 18  presents a screen diagram illustrating the content associated with the context change that may be displayed to a user upon selecting the “play”  1740  option associated with a given buddy&#39;s  1720  gaming context  1780 . 
     According to the embodiment illustrated in  FIG. 18 , a user may engage in the gaming application associated with one or more selected buddies. The context of the selected buddy is delivered to the user&#39;s client device, allowing the user to participate in the gaming application. A user may continue to the view the content  1810  previously selected while taking part in the gaming application. 
     As illustrated in  FIG. 18 , a user&#39;s buddies  1815 ,  1820 ,  1825 ,  1830 ,  1835 ,  1840  and  1845  may be modified to reflect the user&#39;s context change. More specifically, the user&#39;s context, previously comprised only of television content, now comprises both television content  1810  and a poker gaming application  1805 . Therefore, the buddies displayed to a user may be modified to reflect the buddies associated with the changed context. The buddies “joff,” 1835  “hatrick”  1840  and “joymo,”  1845  associated with the user&#39;s television viewing  1810  continue to be displayed on the user&#39;s client device as the user continues to view television content  1810 , whereas the buddies  1815 ,  1820 ,  1825  and  1830  associated with the user&#39;s gaming application  1805  are retrieved and displayed on the user&#39;s client device. The user is further presented with a plurality of controls  1850 ,  1855  and  1860  for participating in the gaming application  1805 . 
     As illustrated in  FIG. 19 , a user may receive one or more alerts while viewing content or participating in a gaming application. According to methods described herein, a user&#39;s profile may identify one or more alerts, wherein alerts may comprise events or notifications that the user wishes to receive or that may be of interest to a given user. A traffic alert  1915  is illustrated, notifying the user of “Major Delays” on a roadway that may be relevant to the user. While the alert presented is a traffic related alert  1915 , other alerts may be displayed on a user&#39;s client device based upon the one or more alerts identified in a user&#39;s profile or the user&#39;s particular context. For example, a user participating in an online poker game may receive an alert notifying the user that a given casino is conducting a poker tournament. Similarly, a user&#39;s profile may indicate that the user wishes to receive an alert notifying the user when the television show “The Real World” will be broadcast. Those of skill in the art recognize other alerts that may be displayed to a user of a client device based upon a user&#39;s profile or a user&#39;s particular context. 
     While the invention has been described and illustrated in connection with preferred embodiments, many variations and modifications as will be evident to those skilled in this art may be made without departing from the spirit and scope of the invention, and the invention is thus not to be limited to the precise details of methodology or construction set forth above as such variations and modification are intended to be included within the scope of the invention.
