PRISM (TV network)

PRISM (Philadelphia Regional In-Home Sports and Movies) is a defunct American regional premium cable television channel in the Philadelphia metropolitan area. Launched in September 1976, PRISM was primarily distributed through area cable systems, although it was also available through a scrambled over-the-air signal on WWSG-TV (channel 57, now WPSG) from 1983 to 1985.

The channel's programming consisted primarily of theatrically released motion pictures, although it was better known for its telecasts of sporting events, particularly those featuring Philadelphia's Major League Baseball, NHL and NBA sports franchises. Due to broadcasting restrictions imposed by the three major sports leagues, as a cable channel, the network limited its distribution to within 125 miles (201 km) of Philadelphia proper (covering an area extending from west of Harrisburg to as far north as Scranton).
