A multicasting download-to-mobile-device service that broadcasts and distributes digital media over cellular networks is described. The most preferred embodiments of the present invention comprise a network that distributes a plurality of media titles (e.g., movies, tv shows, concerts, etc.) via multicast streams where the media titles are stored in local storage on a mobile electronic device (e.g., cellular telephones and tablets) and, by way of a mobile device app, allows users to play the stored media titles locally from their devices using current on demand playback methodologies. In addition, at least some preferred embodiments of the present invention comprise a data carousel that curates and delivers discrete media titles to selected cell towers and/or hubs, thereby providing for relevant media titles to be multicast to discrete regions and not the entire network. Finally, the data carousel may be configured to synchronize relevant titles for discrete users of the service.
