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.
KUHM-TV
The station was originally granted its construction permit on July 23, 1996; on September 16, it was assigned the call letters KAQR. On October 1, 1997, the station changed its call letters to KBCC; on March 27, 1998, channel 10 took on the KMTF call sign. On August 15, 1998, the station started broadcasting as the local Fox affiliate; KMTF also had a secondary affiliation with UPN. On July 1, 2001, due to low ratings and revenue, the station dropped the Fox affiliation and became an affiliate of Pax TV; area cable systems quickly added Foxnet to their lineups to continue carrying Fox programming. After KMTF's affiliation agreement with Pax TV expired in July 2005, the station switched to The WB; the switch made Helena the eighth market in which The WB 100+ Station Group (a predominantly cable-only service that brought WB programming to smaller markets) was seen on an over-the-air station. In September 2006, KMTF became the affiliate for The CW and become part of The CW Plus, the successor of The WB 100+ Station Group.
