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.
KHME
KHME debuted on the air as KOTA-TV, with test operations on June 1, 1955, with regular programming beginning one month later on July 1. It was the second television station in South Dakota, and the first in the western part of the state. The station was owned by Rapid City businesswoman Helen Duhamel, and was a sister station to CBS Radio Network affiliate KOTA (1380 AM). Duhamel bought a minority stake in the radio station in 1943 and gradually expanded her holdings until she bought full control in 1954. Channel 3 originally carried programming from all three networks, though it was a primary CBS television affiliate. Helen's son William (Bill) Duhamel would become KOTA-TV's president and general manager in 1976.
