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.
KITV
The station signed on the air on April 16, 1954, as KULA-TV, launching at 10:30 a.m. with a test pattern, followed by its inaugural sign-on premiere party at 6 p.m., and two movies from 7 p.m. to 9:45 p.m. Prior to its launch, it had planned to use the call letters KABS-TV before settling on the KULA calls, which came from its then sister AM station under the ownership of Pacific Frontier Broadcasting Company, whose owner Jack A. Burnett had applied for a TV license to operate KULA on channel 2 as the channel 4 allocation was being sought after by rival radio stations KGU and KPOA, but after the application by the two stations fell through the FCC awarded the channel 4 allocation to Burnett instead. The station has been an ABC affiliate since its sign-on, making KITV one of the two major television stations in Honolulu that has never changed its network affiliation; local CBS outlet KGMB (originally on channel 9, now on channel 5) is the other. They are also the only station in Hawaii to broadcast in the same channel position since its sign-on. It also shared programming from Dumont with KONA (then at channel 11, now KHON-TV on channel 2), until its demise in 1955.
