KHON-TV
KHON-TV first signed on the air on December 15, 1952 as a primary NBC affiliate, KONA-TV, occupying the channel 11 position. It also had a secondary affiliation with DuMont (which it later shared with KULA-TV, now KITV, after it signed on in 1954) until its demise in 1955. The station, which is Hawaii's second-oldest television station (behind KGMB, originally on channel 9, now on channel 5), was originally owned by Herbert Richards. Two years later in 1954, the "Honolulu Advertiser" purchased the station. On October 16, 1955, KONA changed channels from 11 to 2 due to the lower VHF positions (2 to 6) having the most powerful ERPs at the time. The channel 11 frequency now belongs to PBS member station KHET. In 1956, KONA was sold to Pacific and Southern Broadcasting, the forerunner of Combined Communications. KAII signed on in 1958, with KHAW following in 1961. In 1965, the station's call letters were changed to the current KHON-TV.
KOKH-TV
Blair formally took over KOKH's operations on October 1, 1979, converting it into the first commercial independent station in Oklahoma, and leaving OETA flagship KETA-TV as Oklahoma City's sole educational television station. The station's first broadcast was a special 30-minute program inaugurating the station's new format at 6:00 a.m. that morning; this was followed by KOKH's first entertainment program, the syndicated children's show "New Zoo Revue". It adopted a general entertainment format typical of a UHF-based independent, initially carrying a mix of cartoons, classic sitcoms, religious programs, some sports programming, and certain network programs preempted by NBC affiliate KTVY (channel 4, now KFOR-TV), ABC affiliate KOCO-TV (channel 5) and CBS affiliate KWTV (channel 9) to carry local or syndicated programming (among them, the NBC soap opera "Search for Tomorrow", which KTVY preempted from 1982 to 1985, and "Nightline", which ABC contracted KOKH-TV to show live-to-air from September 1983 to February 1985, after KOCO attempted to push the newsmagazine to a post-midnight slot). The station also heavily incorporated feature films onto its schedule, to such an extent that it was promoted as "Oklahoma's Great[est] Movie Station" from 1979 to 1986; KOKH usually carried four films per day – two each in the afternoon, and one to two films per night in prime time – Monday through Friday, and five to six films per day each weekend.
