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.
KNHL
In 2014, Gray Television, owners of KOLN/KGIN and KSNB-TV, acquired Hoak Media; as it already owned the three aforementioned stations in the same market, it planned to sell KHAS to the shell company Excalibur Broadcasting and operate KHAS under a shared services agreement. As a result of growing FCC scrutiny towards "virtual duopolies", Gray instead let KHAS fall silent on June 13, 2014 and its programming and news operation were relocated to KSNB-TV, pending a sale of KHAS-TV to a minority owned broadcaster. In September 2018, Gray agreed to purchase KNHL, with the intention of operating it as a satellite of KSNB-TV.
