WPSG TV Philadelphia PA

WPSG (channel 57), branded Philly 57, is an independent television station in Philadelphia, Pennsylvania, United States. It is owned by the CBS News and Stations group alongside CBS outlet KYW-TV (channel 3). The two stations share studios on Hamilton Street north of Center City Philadelphia; WPSG's transmitter is located in the city's Roxborough section.

Channel 57 was allocated for commercial use in Philadelphia at the start of the 1970s; it was fought over by two groups who sought to broadcast subscription television (STV) programming to paying customers in the metropolitan area. Radio Broadcasting Company prevailed and launched WWSG-TV on June 15, 1981. It offered limited financial news programming, which was abandoned after 18 months, and a subscription service utilizing programming from SelecTV. Two years later, the station switched to broadcasting PRISM, a premium regional sports and movies service seeking to reach potential subscribers in areas beyond cable coverage, such as the city of Philadelphia.
