s of television broadcasts on certain frequencies, but separately transmitted in FM stereo, along with traditional local radio stations at their specific frequencies, utilizing the cable system's own taller receiving antenna for maximum audio clarity. For instance,
MTV's audio would be offered on a cable radio frequency, thus the video being played in
monaural sound on cable would have its television audio muted, and the stereo audio instead heard through the radio receiver.
A related secondary meaning of the term is any automated music stream - the usual format of cable-only "stations".

The first exclusively cablecasting community radio station was CPVR in
Palos Verdes, California, a suburb of Los Angeles. CPVR 95.9 Cable FM radio was on the
Times-Mirror cable system, and was started by a group of teenagers who initially practiced being disc jockeys in the homes of two of the founders. Since traditional broadcasting equipment was prohibitively expensive at the time, a young engineer named Tom Hewitt built much of the electronic hardware from scratch.
Mark Speer and Brad Gardner began the venture, which was run as a non-profit youth organization from a studio in the Golden Cove shopping center in Rancho Palos Verdes beginning in March 1972. Even though it was non-profit, it was not subject to the restrictions of terrestrial public radio stations, and thus was able to subsidize expenses by accepting commercial advertising.
Because the staff and audience were part of a highly desirable demographic (many of the DJs weren't even old enough to drive), advertisers of the day, such as concert promoter Pacific Presentations and local record stores eagerly bought ad time in order to reach such a prime demographic (males/females, 13-24) as CPVR had attracted during its history, further enabling CPVR to not only continue operations, but expand into larger studios.
Greg McClure (a.k.a. Isaac O. Zzyzx), Jim Sideris, Harv Laser, David Zislis, Richard Hower, Tony Fasola, Dave Chrenko (a.k.a. Johnny Ace), Kerry Doolin, Liane Benson, Lorraine Dechter, Clyde Stanton (a.k.a. Certified Clyde) and Kathy Bauer were some of the young disc jockeys who helped create the station's legendary style and sound. Unlike Cable 108, CPVR was not only on the FM dial, but was in stereo, and also appeared on the cable system's "barker" channel (Channel 3).
Although the station was only on the "cable" for about two years programming free-form rock and roll, CPVR often scooped its over-the-air competitors, breaking acts such as
