CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. patent application Ser. No. 16/042,685, filed on Jul. 23, 2018, which claims priority to U.S. Provisional Application No. 62/539,345, filed Jul. 31, 2017, and entitled “SYSTEMS, DEVICES, AND METHODS FOR PROGRESSIVE ATTACHMENTS.” The contents of these prior applications are considered part of this application, and are hereby incorporated by reference in their entireties. 
    
    
     TECHNICAL FIELD 
     The present disclosure generally relates to the technical field of managing the display of content to users of a social network. Specifically, disclosed are methods for progressively providing more detailed information to a user of a social network based on the user&#39;s request. 
     BACKGROUND 
     Social network members utilize social messaging systems for a variety of purposes. Some members utilize the social messaging system to provide member to member communication, similar to email, which may be available between members. Other members may primarily share content. For example, a first member may upload particular content to the messaging system. The messaging system may alert a second user that the content is available. The second user may then view the content. Because users of social networking systems have varying interests and uses for functionality provided by the social networking system, methods and systems to progressively adapt to requests by the user for information are needed.

     DETAILED DESCRIPTION 
     The description that follows includes systems, methods, techniques, instruction sequences, and computing machine program products that embody illustrative embodiments of the disclosure. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide an understanding of various embodiments of the inventive subject matter. It will be evident, however, to those skilled in the art, that embodiments of the inventive subject matter may be practiced without these specific details. In general, well-known instruction instances, protocols, structures, and techniques are not necessarily shown in detail. 
     Aspects of the present disclosure include systems, methods, techniques, instruction sequences, and computing machine program products that provide for progressive insertion of additional content into a sequence of content based on input from a user. For example, in some aspects, an advertisement may be inserted into a sequence of content being viewed by the user. If the advertisement is of particular interest to the user, the user may indicate a request for additional information. For example, the user may perform a “swipe up” gesture in response to the advertisement to indicate their interest in more information. Upon receiving the request, the social messaging system may present additional content to the user providing further information. In some aspects, this additional content may take the form of a long form video, which describes more detailed information on a particular topic to the user. In response to learning more about the subject area from the additional content, the user may decide to perform additional actions. For example, the additional content may convey benefits associated with installation of a particular third party application on the user&#39;s device. If the user desires the benefits described by the additional content, the user may agree to proceed with an installation of the third party application. Alternatively, the additional content may describe benefits that may be obtained via a web interface. Upon agreement by the user, the social networking system may facilitate a visit to the web interface for the user. For example, the social network system may open the web interface within a browser that is pre-installed on the user&#39;s mobile device. The web interface may provide a number of features useful to the user. 
     In some aspects, a user may select to view a sequence of content. The sequence may be defined, in some aspects, by a chronological order in which the content was added to a messaging system. In other aspects, the sequence may be defined by a user. For example, a first user may arrange content into a particular sequence, such that a second user views the content, the content is presented to the user in the sequence as arranged by the first user. As the second user is viewing the content, additional content may be inserted into the sequence. For example, in some aspects, the additional content may be inserted periodically. 
     In some aspects, the additional content may provide a brief description of a subject area. In some aspects, the additional content may include a short video. The video may provide a brief introduction to a subject area. In some aspects, the additional content may be displayed within a user interface that can accept at least two types of input. A first type of input may request that the user be returned to the sequence of content. For example, a “swipe down” input may indicate that the user requests that the display of the additional content be stopped, and the user returned to the sequence of content. A second type of input may indicate the user requests second additional contet relating to the first additional content. For example, in some aspects, a “swipe up” gesture may signal a request for second additional content. In response to the second type of input, further information may be displayed. In some aspects that utilize a video for the additional content, a longer video may be provided as the second additional information. The second additional information may be displayed in a user interface that also accepts at least two types of input. Similar to the first user interface described above, the second user interface may also accept input requesting a return to the sequence of content. A second type of input may request third additional information. For example, the first additional information may include an installation dialog, enabling the user to install software, or the third additional information may be a web link, enabling the user to link to web content in a browser application. 
       FIG. 1  is a block diagram showing an example messaging system  100  for exchanging data (e.g., messages and associated content) over a network. The messaging system  100  includes multiple client devices  102 , each of which hosts a number of applications including a messaging client application  104 . Each messaging client application  104  is communicatively coupled to other instances of the messaging client application  104  and a messaging server system  108  via a network  106  (e.g., the Internet). As used herein, the term “client device” may refer to any machine that interfaces with a communications network (such as the network  106 ) to obtain resources from one or more server systems or other client devices. A client device may be, but is not limited to, a mobile phone, desktop computer, laptop, portable digital assistant (PDA), smart phone, tablet, ultra book, netbook, laptop, multi-processor system, microprocessor-based or programmable consumer electronics system, game console, set-top box, or any other communication device that a user may use to access a network. 
     In the example shown in  FIG. 1 , each messaging client application  104  is able to communicate and exchange data with another messaging client application  104  and with the messaging server system  108  via the network  106 . The data exchanged between the messaging client applications  104 , and between a messaging client application  104  and the messaging server system  108 , includes functions (e.g., commands to invoke functions) as well as payload data (e.g., text, audio, video, or other multimedia data). 
     The network  106  may include, or operate in conjunction with, an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitan area network (MAN), the Internet, a portion of the Internet, a portion of the Public Switched Telephone Network (PSTN), a plain old telephone service (POTS) network, a cellular telephone network, a wireless network, a Wi-Fi® network, another type of network, or a combination of two or more such networks. For example, the network  106  or a portion of the network  106  may include a wireless or cellular network and the connection to the network  106  may be a Code Division Multiple Access (CDMA) connection, a Global System for Mobile communications (GSM) connection, or another type of cellular or wireless coupling. In this example, the coupling may implement any of a variety of types of data transfer technology, such as Single Carrier Radio Transmission Technology (1×RTT), Evolution-Data Optimized (EVDO) technology, General Packet Radio Service (GPRS) technology, Enhanced Data rates for GSM Evolution (EDGE) technology, third-Generation Partnership Project (3GPP) including 3G, fourth-generation wireless (4G) networks, Universal Mobile Telecommunications System (UMTS), High-Speed Packet Access (HSPA), Worldwide Interoperability for Microwave Access (WiMAX), Long-Term Evolution (LTE) standard, or others defined by various standard-setting organizations, other long-range protocols, or other data transfer technology. 
     The messaging server system  108  provides server-side functionality via the network  106  to a particular messaging client application  104 . While certain functions of the messaging system  100  are described herein as being performed by either a messaging client application  104  or by the messaging server system  108 , it will be appreciated that the location of certain functionality either within the messaging client application  104  or the messaging server system  108  is a design choice. For example, it may be technically preferable to initially deploy certain technology and functionality within the messaging server system  108 , but to later migrate this technology and functionality to the messaging client application  104  where a client device  102  has a sufficient processing capacity. 
     The messaging server system  108  supports various services and operations that are provided to the messaging client application  104 . Such operations include transmitting data to, receiving data from, and processing data generated by the messaging client application  104 . This data may include message content, client device information, geolocation information, media annotation and overlays, message content persistence conditions, social network information, and live event information, as examples. Data exchanges within the messaging system  100  are invoked and controlled through functions available via user interfaces (UIs) of the messaging client application  104 . 
     Turning now specifically to the messaging server system  108 , an Application Programming Interface (API) server  110  is coupled to, and provides a programmatic interface to, an application server  112 . The application server  112  is communicatively coupled to a database server  118 , which facilitates access to a database  120  in which is stored data associated with messages processed by the application server  112 . 
     The API server  110  receives and transmits message data (e.g., commands and message payloads) between the client device  102  and the application server  112 . Specifically, the API server  110  provides a set of interfaces (e.g., routines and protocols) that can be called or queried by the messaging client application  104  in order to invoke functionality of the application server  112 . The API server  110  exposes various functions supported by the application server  112 , including account registration; login functionality; the sending of messages, via the application server  112 , from a particular messaging client application  104  to another messaging client application  104 ; the sending of media files (e.g., images or video) from a messaging client application  104  to the application server  112 , for possible access by another messaging client application  104 ; the setting of a collection of media data (e.g., story); the retrieval of a list of friends of a user of a client device  102 ; the retrieval of such collections; the retrieval of messages and content; the adding and deletion of friends to and from a social graph; the location of friends within a social graph; and the detecting of an application event (e.g., relating to the messaging client application  104 ). 
     The application server  112  hosts a number of applications and subsystems, including a messaging server application  114  and a social network system  116 . The messaging server application  114  implements a number of message processing technologies and functions, particularly related to the aggregation and other processing of content (e.g., textual and multimedia content) included in messages received from multiple instances of the messaging client application  104 . As will be described in further detail, the text and media content from multiple sources may be aggregated into collections of content (e.g., called stories or galleries). These collections are then made available, by the messaging server application  114 , to the messaging client application  104 . Other processor- and memory-intensive processing of data may also be performed server-side by the messaging server application  114 , in view of the hardware requirements for such processing. 
     The social network system  116  supports various social networking functions and services, and makes these functions and services available to the messaging server application  114 . To this end, the social network system  116  maintains and accesses an entity graph within the database  120 . Examples of functions and services supported by the social network system  116  include the identification of other users of the messaging system  100  with whom a particular user has relationships or whom the user is “following,” and also the identification of other entities and interests of a particular user. 
     The disclosed methods and systems may utilize the messaging system  100  to provide for progressive presentation of content on one or more client devices  102 , as explained in more detail below. 
       FIG. 2  is block diagram illustrating further details regarding the messaging system  100 , according to exemplary embodiments. Specifically, the messaging system  100  is shown to comprise the messaging client application  104  and the application server  112 , which in turn embody a number of subsystems, namely an ephemeral timer system  202 , a collection management system  204 , an annotation system  206 , and a progressive attachment system  208 . 
     The ephemeral timer system  202  is responsible for enforcing the temporary access to content permitted by the messaging client application  104  and the messaging server application  114 . To this end, the ephemeral timer system  202  incorporates a number of timers that, based on duration and display parameters associated with a message, or collection of messages (e.g., a story, such as the story component  404  discussed below), selectively display and enable access to messages and associated content via the messaging client application  104 . Further details regarding the operation of the ephemeral timer system  202  are provided below. 
     The collection management system  204  is responsible for managing collections of media (e.g., collections of text, image, video, and audio data). In some examples, a collection of content (e.g., messages, including images, video, text, and audio) may be organized into an “event gallery” or an “event story.” Such a collection may be made available for a specified time period, such as the duration of an event to which the content relates. For example, content relating to a music concert may be made available as a “story” for the duration of that music concert. The collection management system  204  may also be responsible for publishing an icon that provides notification of the existence of a particular collection to the user interface of the messaging client application  104 . 
     The annotation system  206  provides various functions that enable a user to annotate or otherwise modify or edit media content associated with a message. For example, the annotation system  206  provides functions related to the generation and publishing of media overlays for messages processed by the messaging system  100 . For example, the annotation system  206  operatively supplies a media overlay (e.g., a filter) to the messaging client application  104  based on a geolocation of the client device  102 . In another example, the annotation system  206  operatively supplies a media overlay to the messaging client application  104  based on other information, such as social network information of the user of the client device  102 . A media overlay may include audio and visual content and visual effects. Examples of audio and visual content include pictures, texts, logos, animations, and sound effects. An example of a visual effect includes color overlaying. The audio and visual content or the visual effects can be applied to a media content item (e.g., a photo) at the client device  102 . For example, the media overlay may include text that can be overlaid on top of a photograph generated by the client device  102 . In another example, the media overlay includes an identification of a location (e.g., Venice Beach), a name of a live event, or a name of a merchant (e.g., Beach Coffee House). In another example, the annotation system  206  uses the geolocation of the client device  102  to identify a media overlay that includes the name of a merchant at the geolocation of the client device  102 . The media overlay may include other indicia associated with the merchant. The media overlays may be stored in the database  120  and accessed through the database server  118 . 
     In one exemplary embodiment, the annotation system  206  provides a user-based publication platform that enables users to select a geolocation on a map, and upload content associated with the selected geolocation. The user may also specify circumstances under which a particular media overlay should be offered to other users. The annotation system  206  generates a media overlay that includes the uploaded content and associates the uploaded content with the selected geolocation. 
     In another exemplary embodiment, the annotation system  206  provides a merchant-based publication platform that enables merchants to select a particular media overlay associated with a geolocation via a bidding process. For example, the annotation system  206  associates the media overlay of a highest-bidding merchant with a corresponding geolocation for a predefined amount of time. 
     The progressive attachment system  208  may provide for the insertion of content into a sequence of other content. For example, in some aspects, the progressive attachment system  208  may insert content into a sequence of the other content periodically, for example, after a period of time elapses. In some aspects, the progressive attachment system may provide for a user to control an amount of content inserted into the sequence of content. For example, user input may indicate that no further content is to be inserted into the sequence of content after presentation of a first piece of content. Alternatively, the user input may indicate a request to insert additional content into the sequence of content after the user has viewed and considered the first piece of content. 
       FIG. 3  is a schematic diagram  300  illustrating data which may be stored in the database  120  of the messaging server system  108 , according to certain exemplary embodiments. While the content of the database  120  is shown to comprise a number of tables, it will be appreciated that the data could be stored in other types of data structures (e.g., as an object-oriented database). 
     The database  120  includes message data stored within a message table  314 . An entity table  302  stores entity data, including an entity graph  304 . Entities for which records are maintained within the entity table  302  may include individuals, corporate entities, organizations, objects, places, events, etc. Regardless of type, any entity regarding which the messaging server system  108  stores data may be a recognized entity. Each entity is provided with a unique identifier, as well as an entity type identifier (not shown). 
     The entity graph  304  furthermore stores information regarding relationships and associations between or among entities. Such relationships may be social, professional (e.g., work at a common corporation or organization), interested-based, or activity-based, merely for example. 
     The database  120  also stores annotation data, in the example form of filters, in an annotation table  312 . Filters for which data is stored within the annotation table  312  are associated with and applied to videos (for which data is stored in a video table  310 ) and/or images (for which data is stored in an image table  308 ). Filters, in one example, are overlays that are displayed as overlaid on an image or video during presentation to a recipient user. Filters may be of varies types, including user-selected filters from a gallery of filters presented to a sending user by the messaging client application  104  when the sending user is composing a message. Other types of filters include geolocation filters (also known as geo-filters), which may be presented to a sending user based on geographic location. For example, geolocation filters specific to a neighborhood or special location may be presented within a user interface by the messaging client application  104 , based on geolocation information determined by a Global Positioning System (GPS) unit of the client device  102 . Another type of filter is a data filter, which may be selectively presented to a sending user by the messaging client application  104 , based on other inputs or information gathered by the client device  102  during the message creation process. Examples of data filters include a current temperature at a specific location, a current speed at which a sending user is traveling, a battery life for a client device  102 , or the current time. 
     Other annotation data that may be stored within the image table  608  is so-called “lens” data. A “lens” may be a real-time special effect and sound that may be added to an image or a video. 
     As mentioned above, the video table  310  stores video data which, in one embodiment, is associated with messages for which records are maintained within the message table  314 . Similarly, the image table  308  stores image data associated with messages for which message data is stored in the entity table  302 . The entity table  302  may associate various annotations from the annotation table  312  with various images and videos stored in the image table  308  and the video table  310 . 
     A story table  306  stores data regarding collections of messages and associated image, video, or audio data, which are compiled into a collection (e.g., a story or a gallery). The creation of a particular collection may be initiated by a particular user (e.g., a user for whom a record is maintained in the entity table  302 ). A user may create a “personal story” in the form of a collection of content that has been created and sent/broadcast by that user. To this end, the user interface of the messaging client application  104  may include an icon that is user-selectable to enable a sending user to add specific content to his or her personal story. 
     A collection may also constitute a “live story,” which is a collection of content from multiple users that is created manually, automatically, or using a combination of manual and automatic techniques. For example, a “live story” may constitute a curated stream of user-submitted content from various locations and events. Users whose client devices have location services enabled and who are at a common location or event at a particular time may, for example, be presented with an option, via a user interface of the messaging client application  104 , to contribute content to a particular live story. The live story may be identified to the user by the messaging client application  104 , based on his or her location. The end result is a “live story” told from a community perspective. 
     A further type of content collection is known as a “location story,” which enables a user whose client device  102  is located within a specific geographic location (e.g., on a college or university campus) to contribute to a particular collection. In some embodiments, a contribution to a location story may require a second degree of authentication to verify that the end user belongs to a specific organization or other entity (e.g., is a student on the university campus). A content collection may define a sequence of content. For example, the sequence of content may be defined by an order in which the content was inserted into the collection by a user. Alternatively, the sequence may be user defined. For example, an initial sequence may be defined based on the insertion sequence. This insertion sequence may then be subsequently modified via input by the user. For example, the user may be able to drag and drop content within a user interface to define changes to the sequence of content defined by the collection. The methods and systems disclosed herein may insert further content into the sequence of content defined by the collection. 
     The message table  314  may be a relational database table in some aspects, with a row of the table representing a single message. In some aspects, each row in the message table may store content for the message, and a deletion time for the message. As discussed above, the ephemeral timer system  202  may delete messages according to a time associated with the message. For example, when a user creates a message, they may specify a maximum life time of the message, such as by providing an expiration date/time of the message or an amount of time the message is to remain (e.g. 3 hours). This time information may be stored in the message table  314 . As discussed below, in some aspects, the time information may be adjusted based on when certain content may be viewed by a user. Additionally, time remaining for particular content/messages may effect an order in which content is viewed and/or whether additional content is inserted into a sequence of content. 
       FIG. 4  is a block diagram illustrating functional components of the progressive attachment system  208  that forms part of the messaging system  100 , according to some example embodiments. To avoid obscuring the inventive subject matter with unnecessary detail, various functional components (e.g., modules, engines, and databases) that are not germane to conveying an understanding of the inventive subject matter have been omitted from  FIG. 4 . However, a skilled artisan will readily recognize that various additional functional components may be supported by the progressive attachment system  208  to facilitate additional functionality that is not specifically described herein. As shown, the progressive attachment system  208  includes a sequencing component, an insertion component  404 , an input control component  406 , and a presentation component  408 . 
     The content sequencing component  402  identifies a sequence of media that may be presented on a display screen of a client device  102 . The content sequencing component  402  may interface with the collection management system  204  to obtain the sequence of media. For example, the sequence of media may originate from an event story or event gallery as discussed above. The content sequencing component  402  may retrieve the sequence of media from the collection management system  204  in some aspects. 
     The insertion component  404  may be responsible for determining when to insert one or more additional media into the sequence of media. For example, in some aspects, the insertion component may determine an amount of elapsed time since a previous insertion of additional media, and determine a next time for insertion based on the elapsed time. In some aspects, the insertion component may also determine an amount of time since a user registered with the messaging system  100 , and may inhibit insertions until the amount of time reaches a threshold. 
     The input control component  406  may receive input from a user. For example, the input control component may receive inputs indicating a “swipe up” or a “swipe down,” or other inputs that may be provided via a touch device, such as a touch screen display. 
     The presentation component  408  may present media on an electronic display of a client device  102 . In some aspects, the presented media is an image file. In other aspects, the presented media may be a video file. In some aspects, the presented media may be an installation dialog, such as a dialog enabling a user to install additional software on the client device. In some aspects, the presented media may be a web dialog. 
     The above referenced functional components of the progressive attachment system  208  are configured to communicate with each other (e.g., via a bus, shared memory, a switch, or APIs). Collectively, these components facilitate selective presentation of content to users. 
     As is understood by skilled artisans in the relevant computer and Internet-related arts, each functional component illustrated in  FIG. 4  may be implemented using hardware (e.g., a processor of a machine) or a combination of logic (e.g., executable software instructions) and hardware (e.g., memory and the processor of a machine) for executing the logic. For example, any component included as part of the progressive attachment system  208  may physically include an arrangement of one or more processors  410  (e.g., a subset of or among one or more processors of a machine) configured to perform the operations described herein for that component. As another example, any component of the progressive attachment system  208  may include software, hardware, or both, that configure an arrangement of the one or more processors  410  to perform the operations described herein for that component. Accordingly, different components of the progressive attachment system  208  may include and configure different arrangements of such processors  410  or a single arrangement of such processors  410  at different points in time. 
     Furthermore, the various functional components depicted in  FIG. 4  may reside on a single machine (e.g., a client device or a server) or may be distributed across several machines in various arrangements such as cloud-based architectures. Moreover, any two or more of these components may be combined into a single component, and the functions described herein for a single component may be subdivided among multiple components. 
       FIG. 5  shows two exemplary sequences of content display. The display sequence  500  includes media  502   a - d . Media  502   a - d  may originate from an event story or an event gallery, for example, via the collection management system  204 . In some aspects one or more of media  502   a - d  may be an ephemeral message. The ephemeral message may be defined to exist within the social network system  116  for a limited period of time. After the period of time elapses, the ephemeral message may be deleted by the social network system  116   
     The media  502   a - d  may include any form of media. For example, in some aspects, the media  502   a - d  may be images. In other aspects, the media  502   a - d  may be videos. In other aspects, the media  502   a - d  may be a mix of media types, including one or more of images, video, audio, or other forms of media. The media  502   a - d  may be part of a predefined sequence. For example, in some aspects, the sequence may be defined by an order of the media within an event story or an event gallery. In some aspects, the sequence of media may be defined when the media  502   a - d  are added to the event gallery or story. For example, in some aspects, the sequence may be a chronological sequence with respect to times at which the media was added to the event gallery or story. In some aspects, the sequence may be a chronological sequence with respect to a creation time of the media itself, which may be different than a time when the media was added to the event gallery or story. 
     Sequence  525  includes the sequence  500  of media  502   a - d , but also includes an additional media  504 . The additional media  504  may have been inserted between two of the media  502   b  and  502   c  of the sequence  500  ( 502   a - d ). In some aspects, media  504  may be a different type of media than the media  502   a - d . For example, while media  502   a - d  may be video media in some aspects, media  504  may be a fixed image, such as a photo, in some aspects. In other aspects, the media  502   a - d  and  504  may be the same type of media. 
     The additional media  504  may be inserted into the sequence  500  by the insertion component  404  to form the sequence  525 . In some aspects, additional media  504  may provide information on a particular subject. In some aspects, the media  502   a - d  may be media that are included as part of an event gallery or story, for example, as defined by a first user. A second user may then view the first user&#39;s story, and view the media  502   a - d  in an order defined by the sequence  502   a - d . The insertion component  404  may determine, based on one or more criteria, that additional media is to be inserted at some point in the sequence  500 . The exemplary sequence  525  shows the media  504  inserted between the media  502   b  and  502   c  in the sequence. In some aspects, a decision by the insertion component  404  on whether to insert additional media within the sequence  500  may be based on an amount of time remaining in any one or more ephemeral messages included in the content  502   a - d . For example, if the insertion component determines that one or more of the content  502   a - d  may be deleted before a user completes viewing the sequence  500 , the insertion component  404  may determine that additional content is to be inserted, in some aspects, to replace or augment that ephemeral content which is scheduled to be deleted within a threshold period of time. In some aspects, a view rate of content included in the sequence  500  may be determined. For example, a number of content viewed over a period of time may be used to determine the view rate. From this information, the insertion component  404  may estimate a view time of each content in the sequence  500  that has not yet been viewed. The estimated view time may then be compared to a content deletion time of any yet un viewed content within the sequence  500 . If the estimated view time for particular content is after the content&#39;s deletion time, the insertion component may, in some aspects, change an order of the content for viewing such that the ephemeral content is more likely to be viewed before it is deleted. In some other aspects, new content may be inserted before the ephemeral content to augment the sequence of content and compensate for the loss of the ephemeral content before the user is likely to view it. 
       FIG. 6  shows a user interface sequence  600  for displaying the media  502   a - d  of  FIG. 5 . The user interface sequence  600  includes four user interfaces  602   a - d , each interface  602   a - d  displaying media  502   a - d  respectively. The sequence  600  also illustrates that user inputs, shown as exemplary left swipes  610   a - d , may be used to advance the user through the sequence of media  502   a - d  as shown by the user interfaces  602   a - d  respectively. 
     The sequence  600  also shows the insertion of an additional user interface  620 , which displays media  504 . The user interface  620  is configured to receive at least two types of input. A first type of input  630  is shown as an exemplary “swipe up”. A second type of input  632  is shown as an exemplary “swipe down.” Upon receiving the input  632 , the sequence  600  may move from user interface  620 , displaying the media  504 , to the user interface  602   c , which is shown displaying the media  502   c.    
     In some aspects, upon receiving the input  630 , the sequence  600  is shown moving from user interface  620  to user interface  640 . The user interface  640  displays media  645 . In some aspects, media  645  may be a long form video, which may present information on a similar subject as media  504 , but may be a longer video for example, and thus may explain the subject in more depth than media  504  in some aspects. The user interface  645  may accept at least two types of user input. A first type of input  646  may be a “swipe up” gesture. A second type of input  648  may be a “swipe down” gesture. In response to the input  648 , the sequence  600  may transition from user interface  640  back to user interface  620 . Alternatively, in some aspects, in response to the input  648 , the sequence  600  may transition from user interface  640  to user interface  602   c , which displays media  502   c . In response to the input  646 , the sequence  600  may transition from user interface  640  to user interface  660 . If the media  645  is a video, the video may pause at a pause point when the sequence  600  transitions from the user interface  640  to the user interface  660 . If the sequence  600  returns to the user interface  640 , the video may resume from the pause point. 
     The user interface  660  may enable a user to install an addition software application on the device. Alternatively, the user interface  660  may be a web interface. The user interface  660  may receive at least two forms of input. A first form of input  671  may be a “swipe left” gesture in some aspects. The input  671  may trigger additional actions, such as installation of another software application, or opening of a web based interface. In aspects that provide a web interface implementation of user interface  660 , loading of user interfaced  660  maybe initiated in response to the user interface  645  being displayed. By initiating loading of the user interface  660  upon presentation of user interface  645 , delays in displaying the user interface  660  are reduced relative to implementations that would wait to load user interface  660  until it was explicitly requested by the user. 
     A second type of input received by user interface  660  may be a “swipe down” gesture. In response to receiving the input  672 , the sequence  600  may transition from user interface  660  back to user interface  640 . Alternatively, in some aspects, the sequence  600  may transition from user interface  660  to user interface  602   c  in response to input  672 . 
     In some aspects, a swipe up  630  such as that illustrated with respect to content  620 , may suspend ephemeral timers for any of the content  502   a - d . Thus, any estimated deletion times for this content may be moved forward in time while the ephemeral timer(s) are suspended. Upon receiving the swipe down input  632 , the ephemeral timer(s) for content within the sequence  502   a - d  may be resumed. Thus, between the time of a first input (e.g.  630 ) and a second input (e.g.  632 ), with respect to a first content of a sequence of content, one or more ephemeral timers for other content of the sequence of content may be suspended. 
       FIG. 7  is an exemplary embodiment of the user interface  640  of  FIG. 6 . The user interface  640  of  FIG. 7  shows a fixed image  705 . As discussed above, the user interface  640  may receive at least two types of input. A first type of input may request a return to the user interface  620  or  602   c . A second type of input may request additional information, such as that provided by the user interface  660 . A prompt  710  may prompt the user for the second type of information. 
       FIG. 8  is another exemplary embodiment of the user interface  640  of  FIG. 6 . The user interface  640  of  FIG. 8  shows a video  805 . The user interface  640  of  FIG. 8  also shows a progress bar  810  for the video  805 . A pause prompt  815  is also shown. As discussed above, the user interface  640  may accept at least two input types. Prompt  820  prompts the user for the second type of input, which may indicate a request for the information provided by the user interface  660 , as discussed above with respect to  FIG. 6 . 
       FIG. 9  is a flowchart for an exemplary method of selecting content. One or more of the functions discussed below with respect to process  900  and  FIG. 9  may be performed by an electronic hardware processor. For example, instructions stored in an electronic hardware memory may configure the electronic hardware processor to perform one or more of the functions discussed below. For example, in some aspects, instructions stored in the messaging client application  104 , and/or one or more of the content sequencing component  402 , insertion component  404 , input control component  406 , and/or presentation component  408 , may configure a hardware processor, such as the processing unit  1154  of  FIG. 11  or the processor  1204  of  FIG. 12  to perform one or more of the functions discussed below. 
     In block  910 , a sequence of media to present on an electronic display is determined. In some aspects, the sequence of media is presented to a user on a touchscreen of an electronic device, such as a mobile device. In some aspects, the determination may be in response to a user interface selection input, selecting a source of the sequence of media. For example, a user may select an event gallery or an event story. The selected event gallery or event story may be the source for the sequence of media. The sequence of content may be defined by the event gallery or event story. For example, the sequence may be defined based on a sequence in which the media included in the gallery or story were added to the event gallery or event story. Alternatively, the sequence may be defined by a chronological order in which the media was created, edited, or captured. The sequence of media may include two or more media. The media may be any combination of videos, gifs, photos, documents, images, or any media type. 
     In block  920 , a determination is made to present second media between two media of the sequence of media. In some aspects, the determination may be based on an elapsed time since a previous insertion of media into the sequence has been performed. In some aspects, the determination to insert the second media may be based on a content consumption rate of the user. For example, if the user is consuming content at a rate below a rate threshold, and an elapsed time since a previous insertion is above a time threshold, then a determination to insert the second media may be made, and process  900  may move to block  930 . Otherwise, the insertion may not be performed, and process  900  may transition via off-page reference B to block  960 . 
     In block  930 , the second media is presented between the two media. As shown above with respect to  FIG. 6 , in some aspects, a user interface, such as user interface  620  may present the second media (e.g.  504 ). The user interface  620  may be configured to accept two or more types of input in some aspects. 
     In block  940 , a first input is received. As discussed above, the user interface  620  may be configured to receive at least two types of input. The input may be, in some aspects, a gesture entered on a touch screen display, such as that used by a smartphone. 
     Decision block  950  determines whether the input of block  940  requests additional media or requests to return to the sequence of media. If the input requests to return to the sequence of media, process  900  transitions through off-page reference B to present further media in the sequence, as explained below. If the input requests the presentation of additional media, process  900  moves from block  950  to block  960 . As discussed above, the example sequence  600  may transition from the user interface  620  to the user interface  640  upon receiving a particular input, such as an exemplary “swipe up” gesture, such as input  630  in  FIG. 6 . 
     Once presented, the user interface  640  may provide for at least two further inputs. The user interface  640  may be configured to, for example, receive a first input indicating that a return in user interface  620  is requested. A second input may indicate a transition to user interface  660  is requested. 
     After the additional media is presented in block  960 , process  900  transitions via off page reference A to block  965  of  FIG. 10 . In block  965 , a second input is received. The second input may be, in some aspects, a gesture on a touchscreen. For example, the second input may correspond to a “swipe left” or “swipe down” gesture in some aspects on the user interface  640 . Decision block  970  determines whether the second input requests further media be displayed, or a return to the sequence of media is requested. If a return to the sequence is requested, process  900  moves from block  970  to block  980 . Block  980  may present a next media in the sequence after the first media. For example, as shown with respect to  FIGS. 5-6 , after media  502   b  in the sequence of  502   a - d  is presented, media  504  is inserted. After media  504 , the sequence returns by presentation of media  502   c , which is immediately subsequent to media  502   b  in the sequence of media  502   a - d.    
     If further media is requested by the second input, process  900  moves from block  970  to block  975 , which presents the further media. In some aspects, the further media may be presented in a user interface such as user interface  660 , discussed above with respect to  FIG. 6 . 
     Software Architecture 
       FIG. 11  is a block diagram illustrating an example software architecture  1106 , which may be used in conjunction with various hardware architectures herein described.  FIG. 11  is a non-limiting example of a software architecture and it will be appreciated that many other architectures may be implemented to facilitate the functionality described herein. The software architecture  1106  may execute on hardware such as a machine  1200  of  FIG. 12  that includes, among other things, processors  1204 , memory/storage  1206 , and I/O components  1218 . A representative hardware layer  1152  is illustrated and can represent, for example, the machine  1200  of  FIG. 12 . The representative hardware layer  1152  includes a processing unit  1154  having associated executable instructions  1104 . The executable instructions  1104  represent the executable instructions of the software architecture  1106 , including implementation of the methods, components, and so forth described herein. For example, the instructions  1104  may configure the processing unit  1154  to perform one of more of the functions discussed above with respect to process  900 , discussed above with respect to  FIGS. 9 and 10  respectively. The hardware layer  1152  also includes memory and/or storage  1156 , which also have the executable instructions  1104 . The hardware layer  1152  may also comprise other hardware  1158 . 
     As used herein, the term “component” may refer to a device, a physical entity, or logic having boundaries defined by function or subroutine calls, branch points, APIs, and/or other technologies that provide for the partitioning or modularization of particular processing or control functions. Components may be combined via their interfaces with other components to carry out a machine process. A component may be a packaged functional hardware unit designed for use with other components and a part of a program that usually performs a particular function of related functions. 
     Components may constitute either software components (e.g., code embodied on a machine-readable medium) or hardware components. A “hardware component” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various exemplary embodiments, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware components of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware component that operates to perform certain operations as described herein. A hardware component may also be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware component may include dedicated circuitry or logic that is permanently configured to perform certain operations. 
     A hardware component may be a special-purpose processor, such as a Field-Programmable Gate Array (FPGA) or an Application-Specific Integrated Circuit (ASIC). A hardware component may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware component may include software executed by a general-purpose processor or other programmable processor. Once configured by such software, hardware components become specific machines (or specific components of a machine) uniquely tailored to perform the configured functions and are no longer general-purpose processors. It will be appreciated that the decision to implement a hardware component mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations. 
     A processor may be, or include, any circuit or virtual circuit (a physical circuit emulated by logic executing on an actual processor) that manipulates data values according to control signals (e.g., “commands,” “op codes,” “machine code,” etc.) and that produces corresponding output signals that are applied to operate a machine. A processor may, for example, be a Central Processing Unit (CPU), a Reduced Instruction Set Computing (RISC) processor, a Complex Instruction Set Computing (CISC) processor, a Graphics Processing Unit (GPU), a Digital Signal Processor (DSP), an ASIC, a Radio-Frequency Integrated Circuit (RFIC), or any combination thereof. A processor may further be a multi-core processor having two or more independent processors (sometimes referred to as “cores”) that may execute instructions contemporaneously. 
     Accordingly, the phrase “hardware component” (or “hardware-implemented component”) should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. Considering embodiments in which hardware components are temporarily configured (e.g., programmed), each of the hardware components need not be configured or instantiated at any one instance in time. For example, where a hardware component comprises a general-purpose processor configured by software to become a special-purpose processor, the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware components) at different times. Software accordingly configures a particular processor or processors, for example, to constitute a particular hardware component at one instance of time and to constitute a different hardware component at a different instance of time. Hardware components can provide information to, and receive information from, other hardware components. Accordingly, the described hardware components may be regarded as being communicatively coupled. Where multiple hardware components exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware components. In embodiments in which multiple hardware components are configured or instantiated at different times, communications between or among such hardware components may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware components have access. 
     For example, one hardware component may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware component may then, at a later time, access the memory device to retrieve and process the stored output. Hardware components may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information). The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented components that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented component” refers to a hardware component implemented using one or more processors. Similarly, the methods described herein may be at least partially processor-implemented, with a particular processor or processors being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented components. 
     Moreover, the one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an API). The performance of certain of the operations may be distributed among the processors, not only residing within a single machine, but deployed across a number of machines. In some exemplary embodiments, the processors or processor-implemented components may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other exemplary embodiments, the processors or processor-implemented components may be distributed across a number of geographic locations. 
     In the exemplary architecture of  FIG. 11 , the software architecture  1106  may be conceptualized as a stack of layers where each layer provides particular functionality. For example, the software architecture  1106  may include layers such as an operating system  1102 , libraries  1120 , frameworks/middleware  1118 , applications  1116 , and a presentation layer  1114 . Operationally, the applications  1116  and/or other components within the layers may invoke API calls  1108  through the software stack and receive a response as messages  1110 . The layers illustrated are representative in nature and not all software architectures have all layers. For example, some mobile or special-purpose operating systems may not provide a frameworks/middleware  1118  layer, while others may provide such a layer. Other software architectures may include additional or different layers. 
     The operating system  1102  may manage hardware resources and provide common services. The operating system  1102  may include, for example, a kernel  1122 , services  1124 , and drivers  1126 . The kernel  1122  may act as an abstraction layer between the hardware and the other software layers. For example, the kernel  1122  may be responsible for memory management, processor management (e.g., scheduling), component management, networking, security settings, and so on. The services  1124  may provide other common services for the other software layers. The drivers  1126  are responsible for controlling or interfacing with the underlying hardware. For instance, the drivers  1126  include display drivers, camera drivers, Bluetooth® drivers, flash memory drivers, serial communication drivers (e.g., Universal Serial Bus (USB) drivers), Wi-Fi® drivers, audio drivers, power management drivers, and so forth depending on the hardware configuration. 
     The libraries  1120  provide a common infrastructure that is used by the applications  1116  and/or other components and/or layers. The libraries  1120  provide functionality that allows other software components to perform tasks in an easier fashion than by interfacing directly with the underlying operating system  1102  functionality (e.g., kernel  1122 , services  1124 , and/or drivers  1126 ). The libraries  1120  may include system libraries  1144  (e.g., C standard library) that may provide functions such as memory allocation functions, string manipulation functions, mathematical functions, and the like. In addition, the libraries  1120  may include API libraries  1146  such as media libraries (e.g., libraries to support presentation and manipulation of various media formats such as MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG), graphics libraries (e.g., an OpenGL framework that may be used to render 2D and 3D graphic content on a display), database libraries (e.g., SQLite that may provide various relational database functions), web libraries (e.g., WebKit that may provide web browsing functionality), and the like. The libraries  1120  may also include a wide variety of other libraries  1148  to provide many other APIs to the applications  1116  and other software components/modules. 
     The frameworks/middleware  1118  provide a higher-level common infrastructure that may be used by the applications  1116  and/or other software components/modules. For example, the frameworks/middleware  1118  may provide various graphic user interface (GUI) functions, high-level resource management, high-level location services, and so forth. The frameworks/middleware  1118  may provide a broad spectrum of other APIs that may be utilized by the applications  1116  and/or other software components/modules, some of which may be specific to a particular operating system  1102  or platform. 
     The applications  1116  include built-in applications  1138  and/or third-party applications  1140 . Examples of representative built-in applications  1138  may include, but are not limited to, a contacts application, a browser application, a book reader application, a location application, a media application, a messaging application, and/or a game application. The third-party applications  1140  may include an application developed using the ANDROID™ or IOS™ software development kit (SDK) by an entity other than the vendor of the particular platform, and may be mobile software running on a mobile operating system such as IOS™, ANDROID™, WINDOWS® Phone, or other mobile operating systems. The third-party applications  1140  may invoke the API calls  1108  provided by the mobile operating system (such as the operating system  1102 ) to facilitate functionality described herein. 
     The applications  1116  may use built-in operating system functions (e.g., kernel  1122 , services  1124 , and/or drivers  1126 ), libraries  1120 , and frameworks/middleware  1118  to create user interfaces to interact with users of the system. Alternatively, or additionally, in some systems interactions with a user may occur through a presentation layer, such as the presentation layer  1114 . In these systems, the application/component “logic” can be separated from the aspects of the application/component that interact with a user. The applications  1116  may include instructions  1104  that implement the methods discussed herein, such as those discussed above with respect to  FIGS. 9 and/or 10 . 
     Exemplary Machine 
       FIG. 12  is a block diagram illustrating exemplary components (also referred to herein as “modules”) of a machine  1200 . In some aspects, the machine is configured to read instructions from a machine-readable medium (e.g., a machine-readable storage medium) and perform any one or more of the methodologies discussed herein. Specifically,  FIG. 12  shows a diagrammatic representation of the machine  1200  in the example form of a computer system, within which instructions  1210  (e.g., software, a program, an application, an applet, an app, or other executable code) for causing the machine  1200  to perform any one or more of the methodologies discussed herein may be executed. As such, the instructions  1210  may be used to implement modules or components described herein. For example, the instructions  1210  may implement the content selection system  208  in some aspects, which may include, in some of these aspects, one or more of the functions discussed above with respect to  FIGS. 9 and 10 . The instructions  1210  transform the general, non-programmed machine  1200  into a particular machine  1200  programmed to carry out the described and illustrated functions in the manner described. In alternative embodiments, the machine  1200  operates as a standalone device or may be coupled (e.g., networked) to other machines. In a networked deployment, the machine  1200  may operate in the capacity of a server machine or a client machine in a server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine  1200  may comprise, but not be limited to, a server computer, a client computer, a personal computer (PC), a tablet computer, a laptop computer, a netbook, a set-top box (STB), a personal digital assistant (PDA), an entertainment media system, a cellular telephone, a smart phone, a mobile device, a wearable device (e.g., a smart watch), a smart home device (e.g., a smart appliance), other smart devices, a web appliance, a network router, a network switch, a network bridge, or any machine capable of executing the instructions  1210 , sequentially or otherwise, that specify actions to be taken by machine  1200 . Further, while only a single machine  1200  is illustrated, the term “machine” shall also be taken to include a collection of machines that individually or jointly execute the instructions  1210  to perform any one or more of the methodologies discussed herein. 
     The machine  1200  may include processors  1204 , memory/storage  1206 , and I/O components  1218 , which may be configured to communicate with each other such as via a bus  1202 . The memory/storage  1206  may include a memory  1214 , such as a main memory, or other memory storage, and a storage unit  1216 , both accessible to the processors  1204  such as via the bus  1202 . The storage unit  1216  and memory  1214  store the instructions  1210  embodying any one or more of the methodologies or functions described herein. The instructions  1210  may also reside, completely or partially, within the memory  1214 , within the storage unit  1216 , within at least one of the processors  1204  (e.g., within the processor&#39;s cache memory), or any suitable combination thereof, during execution thereof by the machine  1200 . Accordingly, the memory  1214 , the storage unit  1216 , and the memory of the processors  1204  are examples of machine-readable media. 
     As used herein, the term “machine-readable medium,” “computer-readable medium,” or the like may refer to any component, device, or other tangible medium able to store instructions and data temporarily or permanently. Examples of such media may include, but are not limited to, random-access memory (RAM), read-only memory (ROM), buffer memory, flash memory, optical media, magnetic media, cache memory, other types of storage (e.g., Electrically Erasable Programmable Read-Only Memory (EEPROM)), and/or any suitable combination thereof. The term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) able to store instructions. The term “machine-readable medium” may also be taken to include any medium, or combination of multiple media, that is capable of storing instructions (e.g., code) for execution by a machine, such that the instructions, when executed by one or more processors of the machine, cause the machine to perform any one or more of the methodologies described herein. Accordingly, a “machine-readable medium” may refer to a single storage apparatus or device, as well as “cloud-based” storage systems or storage networks that include multiple storage apparatus or devices. The term “machine-readable medium” excludes transitory signals per se. 
     The I/O components  1218  may include a wide variety of components to provide a user interface for receiving input, providing output, producing output, transmitting information, exchanging information, capturing measurements, and so on. The specific I/O components  1218  that are included in the user interface of a particular machine  1200  will depend on the type of machine. For example, portable machines such as mobile phones will likely include a touch input device or other such input mechanisms, while a headless server machine will likely not include such a touch input device. It will be appreciated that the I/O components  1218  may include many other components that are not shown in  FIG. 12 . The I/O components  1218  are grouped according to functionality merely for simplifying the following discussion and the grouping is in no way limiting. In various exemplary embodiments, the I/O components  1218  may include output components  1226  and input components  1228 . The output components  1226  may include visual components (e.g., a display such as a plasma display panel (PDP), a light emitting diode (LED) display, a liquid crystal display (LCD), a projector, or a cathode ray tube (CRT)), acoustic components (e.g., speakers), haptic components (e.g., a vibratory motor, resistance mechanisms), other signal generators, and so forth. The input components  1228  may include alphanumeric input components (e.g., a keyboard, a touch screen configured to receive alphanumeric input, a photo-optical keyboard, or other alphanumeric input components), point-based input components (e.g., a mouse, a touchpad, a trackball, a joystick, a motion sensor, or other pointing instruments), tactile input components (e.g., a physical button, a touch screen that provides location and/or force of touches or touch gestures, or other tactile input components), audio input components (e.g., a microphone), and the like. The input components  1228  may also include one or more image-capturing devices, such as a digital camera for generating digital images and/or video. 
     In further exemplary embodiments, the I/O components  1218  may include biometric components  1230 , motion components  1234 , environment components  1236 , or position components  1238 , as well as a wide array of other components. For example, the biometric components  1230  may include components to detect expressions (e.g., hand expressions, facial expressions, vocal expressions, body gestures, or eye tracking), measure biosignals (e.g., blood pressure, heart rate, body temperature, perspiration, or brain waves), identify a person (e.g., voice identification, retinal identification, facial identification, fingerprint identification, or electroencephalogram-based identification), and the like. The motion components  1234  may include acceleration sensor components (e.g., accelerometer), gravitation sensor components, rotation sensor components (e.g., gyroscope), and so forth. The environment components  1236  may include, for example, illumination sensor components (e.g., photometer), temperature sensor components (e.g., one or more thermometers that detect ambient temperature), humidity sensor components, pressure sensor components (e.g., barometer), acoustic sensor components (e.g., one or more microphones that detect background noise), proximity sensor components (e.g., infrared sensors that detect nearby objects), gas sensors (e.g., gas detection sensors to detect concentrations of hazardous gases for safety or to measure pollutants in the atmosphere), or other components that may provide indications, measurements, or signals corresponding to a surrounding physical environment. The position components  1238  may include location sensor components (e.g., a GPS receiver component), altitude sensor components (e.g., altimeters or barometers that detect air pressure from which altitude may be derived), orientation sensor components (e.g., magnetometers), and the like. 
     Communication may be implemented using a wide variety of technologies. The I/O components  1218  may include communication components  1240  operable to couple the machine  1200  to a network  1232  or devices  1220  via a coupling  1224  and a coupling  1222  respectively. For example, the communication components  1240  may include a network interface component or other suitable device to interface with the network  1232 . In further examples, the communication components  1240  may include wired communication components, wireless communication components, cellular communication components, Near Field Communication (NFC) components, Bluetooth® components (e.g., Bluetooth® Low Energy), Wi-Fi® components, and other communication components to provide communication via other modalities. The devices  1220  may be another machine or any of a wide variety of peripheral devices (e.g., a peripheral device coupled via a USB). 
     Moreover, the communication components  1240  may detect identifiers or include components operable to detect identifiers. For example, the communication components  1240  may include Radio Frequency Identification (RFID) tag reader components, NFC smart tag detection components, optical reader components (e.g., an optical sensor to detect one-dimensional bar codes such as Universal Product Code (UPC) bar code, multi-dimensional bar codes such as Quick Response (QR) code, Aztec code, Data Matrix, Dataglyph, MaxiCode, PDF4111, Ultra Code, UCC RSS-2D bar code, and other optical codes), or acoustic detection components (e.g., microphones to identify tagged audio signals). In addition, a variety of information may be derived via the communication components  1240 , such as location via Internet Protocol (IP) geo-location, location via Wi-Fi® signal triangulation, location via detecting an NFC beacon signal that may indicate a particular location, and so forth.
