An electronic program guide for the radio (radio EPG) depicts radio programs available via the Internet or analog transmission. The radio EPG displays the programming available for a plurality of radio stations and time slots. The radio EPG is interactive in that a user may select a radio program for immediate playback or future recording. Radio programs are continuously received and cached by the Internet-enabled television system such that a user may be able to select and listen to an earlier-broadcast radio program listed in the radio EPG. The EPG is broadcast using a wireless technology so that mobile devices such as cellular phones, webpads, personal desktop assistants (PDA's), personal stereos, car stereos, and laptop computers with wireless network connections can receive and display the EPG.
