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.
KMPH-TV
The station first signed on the air on October 11, 1971; originally operating as an independent station, it was the first television station founded by the Pappas brothers, Mike, Pete and Harry, through their company, Pappas Television. The brothers already owned radio stations KGEN (1370 AM) and KBOS (94.9 FM) in Tulare, KMPH's original city of license. The station's original studios were located on Mooney Boulevard in Visalia. The funding for KMPH came from general manager Harry Pappas' plan of having hundreds of investors each investing a small amount of money that was needed to construct the station, rather than having one investor providing all the capital; as a result, the Pappas brothers had a combined ownership stake of only 30.5%, with the other 69.5% controlled by other investors.
