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.
KWTX-TV
Long plagued by financial difficulties due to being the only UHF station in the market at a time when UHF tuners were rare, KANG, owned by Texas Broadcasting Company, shut down at the end of 1955. KWTX bought KANG's assets in exchange for a 29% share in the combined operation. KWTX picked up the CBS affiliation as a result of the merger with KANG, and has been a primary CBS affiliate ever since. It shared a secondary ABC affiliation with KCEN-TV (channel 6) until 1983. KCEN later briefly switched to being a full-time ABC affiliate.
