criteria and legally be considered a national superstation. While the FCC defines "superstation" as a term, it does not prohibit its use by others outside of that scope; for example, primary ABC/subchannel-only CW affiliate KYUR (channel 13) in Anchorage – which has a network of repeater stations in other parts of Alaska – had collectively branded its main station and repeaters as "The Alaska SuperStation" from 1996 to 2011. Some Spanish language networks like Telemundo and Univision may only have one station within an entire state that serves the largest city in their market and is distributed statewide via cable; one such case is Telemundo affiliate WYTU-LD (channel 63) in Milwaukee, which maintains cable distribution throughout Wisconsin via Charter Spectrum, along with extended coverage on low-power stations in Rockford, Illinois, and South Bend, Indiana, providing it broad coverage resembling a regional superstation though not marketing itself as such. The term has been (and, in a few cases, currently is) used by many other television and radio stations, but none of these operations is a superstation as defined by the FCC and solely use the term for marketing purposes. Similarly, the "superstation" term has also been occasionally stretched within the broadcasting industry to encompass major network affiliates imported by satellite common carriers to C-band and direct broadcast satellite providers—through packages such as Primetime 24 and its associated "Denver 5" tier, and the Netlink-distributed A3 package—that could not receive locally based network stations prior the implementation of the Satellite Television Extension and Localization Act in 1999. United States Early television superstations In the early days of television broadcasting, most large media markets – primarily those ranked among the top 20 in Arbitron and Nielsen estimates – had, by standards of the period, a sizeable number of television stations (sometimes as many as eight or nine in operation). Generally, these markets had three VHF stations that operated as affiliates of the then dominant television networks – NBC, ABC, CBS, and FOX – one or more public television stations – which usually were member stations of National Educational Television (NET) and its later successor, the Public Broadcasting Service (PBS) – and one or more UHF stations, and in the largest markets (such as New York City, Los Angeles and Chicago), at least one VHF station without a network affiliation. These independent stations generally relied on syndicated reruns of current or defunct network shows, classic
