The station was originally based in studios located at 650 California Street. Several key scenes from the Robert Redford-starring political election intrigue movie "The Candidate" (1970) were filmed in KBHK's studio at 420 Taylor Street (originally NBC "Red Network" Radio Studios). Many of KBHK's technicians appeared in the movie as themselves. Kaiser Broadcasting later merged with Chicago-based Field Communications (Marshall Field, (1834–1906, founder of empire including famous department store chain and later descendants branching into media with broadcasting flagship TV station WFLD among others, and daily newspaper, the "Chicago Sun-Times" and defunct tabloid "Chicago Daily News") in 1973 as part of a joint venture between the companies. In 1977, Kaiser sold its interest in the stations to Field, making Field the sole owner of KBHK. Field later put its stations up for sale in 1982, and KBHK was sold to United Television in 1983. KBHK maintained a general entertainment program schedule that included morning and afternoon children's blocks, off-network sitcoms (such as "The Brady Bunch"), feature films, and public affairs programming. At one point, KBHK advertised itself as the "Bay Area's Movie Station" and aired a movie in prime time six nights a week. At various times during the 1970s and 1980s, KBHK was the flagship TV affiliate of the Oakland Athletics, pre-empting regular programming to telecast the baseball games.
