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.
KENS
In 1951, Storer Broadcasting (which had good relations with CBS) bought KEYL and KABC. On February 1, 1954, channel 5 changed its call letters to KGBS-TV; KABC's calls were subsequently changed to match its television sister, as KGBS, on March 1. In November of that year, Storer was forced to sell KGBS-AM-TV to the "San Antonio Express-News", in order to complete the company's purchase of WXEL-TV (now WJW) in Cleveland, Ohio as keeping KGBS-TV would have put the company one station over the Federal Communications Commission's ownership regulations that went into effect that year which limited the number of television stations that can be owned by one company to seven, with no more than five of those allocated to the VHF band (at the time, newspapers could own television and/or radio stations in the same market provided that such ownership complied with the FCC-mandated ownership limits of each property in effect at the time). The "Express-News" then changed the call letters of the television and radio stations to KENS-TV and KENS (the "-TV" suffix was dropped from the callsign of the television station following the digital television transition on June 12, 2009, when several other Belo stations dropped the suffix from their legal call signs; Storer later re-used the KGBS calls on what is now KTNQ and KAMP-FM in Los Angeles).
