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.
KHQ-TV
While KHQ and KXLY were both granted authorization by the Federal Communications Commission (FCC) to build television stations on July 12, 1952, KHQ was first to sign on the air, going live on Saturday, December 20, 1952 at 6 p.m. with the film "Texas Trouble Shooters". The first NBC program KHQ broadcast was an episode of "Your Hit Parade", which aired that evening at 7:30. In addition to being the oldest television station east of the Cascades, KHQ is also the second-oldest station in Washington state. It was co-owned by Cowles Publishing along with KHQ radio (AM 590, now KQNT; and FM 98.1, now KISC). The radio stations were both sold off in 1985.
