Abstract
Abstract The system enables listeners and viewers of a broadcast to access additional information associated with a broadcast. Listeners and viewers utilize a user device to connect to a database containing program descriptions (e.g. audio, text, video, or combination thereof) further describing the programming and ancillary information. The database is indexed by the broadcast's program list or schedule thereby allowing a user of the system to search and select a particular program description of interest. Hearing or viewing program descriptions enables users to preview excerpts and review a broadcast before purchasing an item heard or viewed on a broadcast.
