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.
KTVG-TV
KTVG and KSNB-TV dropped the secondary UPN affiliation in January 1998; however, the network's programming returned in late 2000, and would remain until KOLN (channel 10) and KGIN (channel 11) launched a UPN-affiliated subchannel on September 1, 2005. The network shut down a year later in favor of The CW, which was seen on KCWL-TV (channel 51) until June 2009, when it became KFXL-TV and started simulcasting KSNB/KTVG. Also in 2000, KSNB and KTVG added a secondary affiliation with Pax TV, renamed i: Independent Television on July 1, 2005 and Ion Television on January 29, 2007. The Ion affiliation was later discontinued.
