By the mid 1960s, more sets were being equipped to receive UHF signals and this led to additional UHF stations, beginning on January 2, 1968, with KBHK, operating on Channel 44, a station owned by Kaiser Broadcasting. In 1968, KSAN was acquired by Metromedia and renamed KNEW, then donated to KQED in 1970, which operated it as a secondary PBS channel under the call letters KQEC. The station changed hands again in 1988, becoming a foreign language station known as KMTP-TV.
