Superstation (alternatively rendered as "super station" or informally as "SuperStation") is a term in North American broadcasting that has several meanings. Commonly, a "superstation" is a form of distant signal, a broadcast television signal—usually a commercially licensed station—that is retransmitted via communications satellite or microwave relay to multichannel television providers (including cable, direct broadcast satellite and IPTV services) over a broad area beyond its primary terrestrial signal range.
Outside of their originating media market, superstations are often treated akin to a conventional basic cable channel. Although six American television stations—none of which has widespread national distribution beyond home satellite or regional cable coverage—still are designated under this classification, these stations were primarily popularized between the late 1970s and the 1990s, in large part because of their carriage of sporting events from local professional sports franchises and theatrical feature films, offerings that were common of the time among independent stations that composed the superstation concept. These signals were also popular among C-band satellite subscribers in rural areas where broadcast signals could not be picked up off-air.
Individual radio stations have also been redistributed via satellite as superstations through cable radio services offered by television providers and standalone satellite radio services. In other parts of North America, the definition of what may constitute even a de facto superstation varies depending on the country and the overall availability of the distributed stations.
