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.
KABC-TV
Channel 7 first signed on the air under the callsign KECA-TV on September 16, 1949. At the same time, it was the last television station licensed to Los Angeles operating on the VHF band to sign on, and the last of ABC's five original owned-and-operated stations to make its debut (after San Francisco's KGO-TV, which signed on four months earlier). It was also the last of the Los Angeles "classic seven" TV stations to sign on (all of them were originally on the VHF dial, prior to the 2009 digital conversions). In addition, it was the last new Los Angeles TV station to sign on from 1949 until 1962 when the first two UHF Los Angeles stations launched (they were KIIX [now KWHY-TV] and KMEX-TV, channels 22 and 34, respectively).
