ABSTRACT:
A plurality of users each selects desired listening broadcast programs that are recorded by a system in a memory and indexed to the specific user. The user may also select the desired playback schedule and playback format. Conveniently, the system retrieves recorded broadcast programs stored in memory, then plays them according to the specific user's desired format and schedule. Additionally, each user may select which broadcast programs are stored, which broadcast frequencies are scanned by the system for the desired broadcast programs, and how long each broadcast program is stored in memory.
