A media content delivery system includes a network server in communications with a plurality of mobile communication devices. The network server maintains a map of geo-fence instances and corresponding geographic locations of each, and it maintains a store of media content that relates to each geographic location. Each of the communication devices has functionality that operates to determine its current geographic location and to send the current geographic location to the network server. The network server runs a logical process that determines if a current location of the mobile device corresponds to a geo-fence location, and if so, operates to determine whether the user is waiting in a queue defined by the geo-fence. If both of these conditions are satisfied, the server selects and delivers media content to the mobile device that relates in some manner to a venue associated with the identified geo-fence instance.
