'''Cable radio''' is [[radio broadcasting]] into homes and businesses via a cable. This can be a [[coaxial cable]] used for television, or a telephone line. It is generally used for the same reason as cable TV was in its early days when it was "community antenna television", in order to enhance the quality of over-the-air radio signals that are difficult to receive in an area. However, cable-only radio outlets also exist. It can be both FM or AM.

The use of cable radio varies from area to area - some cable TV systems don't include it at all, and others only have something approaching it on [[digital cable]] systems. Additionally, some stations may just transmit audio in the background while a [[public-access television]] cable TV channel is operating in between periods of video programming.

From the late 1970s to the late 1980s, before the advent of [[Multichannel Television Sound|MTS Stereo]] television broadcasts, an additional cable decoder was offered to cable TV subscribers, which was connected to the FM antenna terminal of a radio receiver and broadcast audio [[simulcast]]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|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".
