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.
KNUZ-TV
KNUZ-TV, UHF analog channel 39, was a DuMont-affiliated television station licensed to Houston, Texas, United States. It signed on the air on October 23, 1953, as Houston's fourth television station and first UHF station. KNUZ-TV's studios were located at 4343 Cullen Boulevard in the Texas Television Center on the University of Houston campus. The station went dark on June 25, 1954; its studio facility and equipment were acquired by upstart ABC affiliate (now owned-and-operated station) KTRK-TV (channel 13) in order to expedite its debut. KTRK began broadcasting with the acquired assets a few months later, on November 20, 1954.
The studios were used by KTRK-TV until they moved to their current studio on Bissonnet Street in 1961. Then the studios were occupied by KUHT in 1964 and remained there for 35 years. Eventually, they departed across campus to the current LeRoy and Lucile Melcher Center for Public Broadcasting facility in 2000.
