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.
KCRA-TV
The station first signed on the air on September 3, 1955. It was founded by the Central Valley Broadcasting Company, a partnership of the Kelly and Hansen families of Sacramento. Central Valley Broadcasting also owned KCRA radio (1320 AM, now KIFM, and 96.1 FM, now KYMX); the AM station's call letters were intended to be KRCA, but the middle two letters were erroneously transposed by a typist at the Federal Communications Commission (FCC) when that station's original license was drafted in 1945 and was never corrected. By the time KCRA-TV went on the air, the "KRCA-TV" call letters had already been taken the previous year by NBC's owned-and-operated station in Los Angeles (originally KNBH, now KNBC). The station's longtime original studios were located at 310 10th Street in Sacramento. KCRA-TV inherited the NBC affiliation from KCCC-TV (channel 40, channel now occupied by Fox affiliate KTXL), which became the Sacramento market's first television station when it signed on in September 1953, which had also carried affiliations with ABC, CBS and DuMont until other stations debuted in the market. However, it in turn also received the affiliation as a result of KCRA-AM's decade-long affiliation with the NBC Red Network. KCRA was the third of Sacramento's VHF stations to sign on exactly within a year behind KXTV and KOVR—all signing on in six-month increments.
