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.
WKBN-TV
The station went on-the-air January 11, 1953 as the first UHF station in Ohio and the sixth in the nation, beating WFMJ-TV to the air by 56 days. It was owned by the Williamson family along with WKBN radio (AM 570 and FM 98.9, now WMXY) as part of the WKBN Broadcasting Corporation. The radio station was a CBS Radio affiliate, and out of loyalty, the television station has been a primary CBS affiliate from the beginning. It also had secondary affiliations with ABC and DuMont. Shortly afterward, WKST-TV in nearby New Castle, Pennsylvania (now WYTV) signed-on and took the ABC affiliation. With DuMont off-the-air three years later, WKBN was solely affiliated with CBS by the end of 1956.
