The origins of modem superstations can be traced back to the start of distant signal importation by early cable (CATV) systems using microwave relays. At first, the relays simply brought signals to communities too remote to receive them using rooftop or community antennas, but as cable systems began to penetrate television markets with one or more local stations, operators often would import the signals of popular, well­ financed stations from major metropolitan areas to make their service more appealing to potential subscribers. In effect, the distant signals were combined with local signals to create a distinct cable programming package. All of today's superstations were carried by microwave at one time; however, the actual term "superstation" was not used until the late 1970s, shortly after Ted Turner's Atlanta, Georgia, station, WTBS, became the first independent station to be carried by satellite.

     Not only was Turner's station the first satellite­ delivered independent station (and the second satellite­ delivered cable program service overall), it was an innovator in the type of programming that would be most successful on cable. As with many cable-only program services, the popularity of superstations stems largely from their numerous movie screenings and extensive sports coverage-program types available in much smaller quantities from the broadcast networks and their affiliates. Superstation status also gives an independent station an economic advantage when competing with other stations for the broadcast rights to popular syndicated series. The evolution of WTBS's successful program schedule represents an aggressive effort to acquire these sorts of programs.

     The existence of WTBS dates back to 1968, when Turner purchased a failing UHF (ultrahigh frequency) station. He quickly changed the fortunes of his new station (which he called WTCG during its early years) by using old movies and syndicated television series to counterprogram network affiliate stations. going after such audience segments as children and people not watching the news. By the early 1970s, Turner's station also offered local sports programming: first professional wrestling and later baseball, basketball, and hockey. By 1972, WTCG had become popular enough in the Atlanta metropolitan area that its signal had begun to be carried by microwave to cable systems throughout Georgia and northern Florida. In 1976, when Turner uplinked his signal to a communications satellite, WTCG's potential coverage was extended to locations as distant as Canada and Alaska. The station was renamed WTBS (for Turner Broadcasting System) in the late 1970s to reflect the scope of its new operations.

     Within the next few years, the signals of other major-market independent stations also began to be carried on satellite. However, the stations that followed WTBS to satellite carriage represent a different category of superstation. WTBS is considered to be an "active" superstation because it pursues superstation status as part of day-to-day operations: programming targets a nationwide market more than a local market, and national advertising is sought. WTBS currently is the only active superstation.

     "Passive" superstations, by contrast, traditionally have done little or nothing to acknowledge themselves as superstations. Satellite common carriers such as United Video, Inc., and EMI Communications Corp. retransmit the stations' signals without any formal consent, sometimes against the stations' wishes. Despite their potential to be viewed thousands of miles away, passive superstations have continued to direct the greater portion of their programming and advertising toward local or regional markets. As with any cable program service. cable operators pay per-subscriber fees for the use of passive superstations' signals. However, the fees are paid to the common carriers, not to the stations.

     As cable's popularity continues, passive superstitions are giving more recognition to their own super­ station status, often having an employee who functions as a liaison to the satellite carrier and possibly to the cable systems taking the service . Nonetheless, most continue to feel that their priorities remain with their local markets.

     The five "passive" superstations currently in operation are: WOR and WPIX. New York; WSBK, Boston; WGN. Chicago; KTLA. Los Angeles; and KTVT, Dallas, Texas. It is worth noting that this group includes some of the country's most long-standing broadcast stations. Like WTBS, these stations have been extremely successful in counterprogramming other stations. All carry local sports, for example, WOR features Mets baseball, WPIX the Yankees, WSBK the Red Sox, WGN the Cubs, KTLA the Dodgers, and KTVT the Rangers. All these stations also carry other sports teams. Most also feature regularly scheduled movie programs, often with well-known hosts. Since the late 1990s, several of the passive superstations have opted to affiliate with the new broadcast "mininetworks" (United Paramount Network [UPN] and The WB), enhancing their own programming schedules as well as providing additional viewership for the new networks. For example, Chicago's WGN is affiliated with The WB network.

     The popularity of independent stations as cable program services has surprised many, particularly those who have touted cable's potential to provide programming substantially different from that of broadcast television. This popularity indicates quite a lot about the economics of satellite-served cable. a new vehicle for television programming that has had to compete with the established and resource-laden broadcast networks. In many instances, the formula for success has been found in program schedules that are familiar to television audiences but that nonetheless differ from those of the "big three" networks (American Broadcasting Company [ABC], National Broadcasting Company [NBC], and Columbia Broadcasting System [CBS])---a formula that independent stations have been following for decades.
