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.

On November 20, 2013, Gray Television announced it would purchase Hoak Media in a $335 million deal. As Gray already owned KOLN/KGIN, KHAS was to be sold to Excalibur Broadcasting and operated by Gray under a local marketing agreement. However, in the wake of heightened FCC scrutiny of local marketing agreements, on June 11, 2014, KHAS-TV announced it would leave the air at midnight on June 13 and NBC programming would be moved to KSNB-TV and the digital subcarrier of KOLN/KGIN. KHAS would then be sold off to minority interests, which under this arrangement would allow the station to return to the air on the conditions that the new owner operate the station independently (under minority, female and/or non-profit ownership) and not make any partnerships or sharing arrangements with other broadcasters.
