Square, home to KTTV. The gulf between KBSC-TV and its sister stations grew wider. In August 1972, Kaiser transferred the licenses for five of its stations to a partnership with Field Communications, of which it would own 77.5 percent. KBSC-TV was held out of the joint venture because it was scheduled to be sold. Two months later, Kaiser announced it would seek to sell the station to the Pay Television Corporation in a transaction filed with the FCC in February 1973. The largest owner of Pay Television Corporation was Jean Marieanne McDonald. The application remained pending at the FCC for nearly two years; ultimately, the company opted to franchise its technology and not be a station owner, resulting in the purchase being canceled in February 1975. The ON TV years In December 1975, Kaiser filed to sell KBSC-TV to Oak Broadcasting Systems, a joint venture of television equipment manufacturer Oak Industries and Jerry Perenchio. The $1.2 million transaction, which closed the next year, set the course for channel 52 to become the first station in their planned subscription television venture, as Oak moved the studios from Metromedia Square to a site on Grand Central Avenue in Glendale. On April 1, 1977, 500 test subscribers in the San Fernando Valley became the first customers of ON TV, a subscription service broadcast over KBSC-TV that offered unedited, uninterrupted motion pictures, as well as limited slates of Los Angeles Dodgers, California Angels, Los Angeles Lakers and Los Angeles Kings games, during evening hours. It was the second subscription television system in operation, with Wometco Home Theater having launched in New York City the previous month. Japanese- and Korean-language programs that were seen on channel 52 under leased-time arrangements migrated to a new station, KSCI (channel 18), when it launched on June 30; this allowed ON TV to air during evening hours beginning at 8:00 pm. ON TV proved to be a success in its early years of operation, and nowhere was this more apparent than in Southern California, despite the arrival of SelecTV on KWHY-TV (channel 22) the next year. By April 1979, the service was signing up 12,000 subscribers a month. By that year, it had grown its sports portfolio beyond the Dodgers, Angels, Lakers, and Kings to include USC Trojans college sports and Los Angeles Aztecs soccer, as well as horse racing from Santa Anita Park.
