A computerized method for engaging a user of a mobile computer system, wherein the mobile computer system is connectible to a server over a wide area network, the computerized method comprising: autonomously sampling an audio signal of ambient audio in the vicinity of the mobile computer system, thereby capturing an audio sample of the audio signal without an input from the user; caching said audio sample thereby storing said audio sample with a corresponding time stamp in a storage of the mobile computer system; processing said audio sample, thereby extracting an audio signature of said audio sample; comparing said audio signature with a plurality of previously stored reference audio signatures; upon matching said audio signature with at least one reference audio signature thereby producing a matched reference audio signature, performing an action to engage the user, wherein said action is associated with said at least one matched reference audio signature; receiving from said server, information identifying a trigger event and a broadcast time associated with said trigger event; and upon receipt of said trigger event information, transmitting at least one of said audio sample audio signature to the server when said time stamp falls within a predetermined time interval that includes the broadcast time.
