KTVB (channel 7) is a television station in Boise, Idaho, United States, affiliated with NBC and owned by Tegna Inc. The station's studios are located on West Fairview Avenue (off I-184) in Boise, and its transmitter is located at the Bogus Basin ski area summit in unincorporated Boise County. The station also operates a low-power repeater in Twin Falls, KTFT-LD (channel 7). The two signals are identical, with the exception of commercials, which are sold and targeted to the Magic Valley area. KTFT maintains a small advertising sales office on Falls Avenue in Twin Falls and transmitter on Flat Top Butte near Jerome, Idaho. Master control and most internal operations are based at KTVB's facilities. History The station, Idaho's oldest (but not its first), signed on July 12, 1953, as KIDO-TV. Along with radio station KIDO, it was originally owned by Georgia Davidson, who was one of only three female station owners in the NBC network including Dorothy Bullitt of future sister station KING-TV in Seattle. Davidson sold KIDO radio in 1959 but kept KIDO-TV, which she renamed KTVB on February 1. KTVB has always been a primary NBC affiliate, owing to KIDO radio's longtime relationship with the NBC Radio Network. After KBOI-TV (channel 2, CBS) signed on in November 1953, the two stations briefly shared secondary DuMont affiliations, and shared secondary ABC affiliations until KITC (channel 6) signed on in 1974. Before PBS member KAID-TV (channel 4) signed on in December 1971, KTVB preempted the second hour of the Today Show to carry Sesame Street without commercials on weekday mornings. In the early 1960s, KTVB built a satellite station in La Grande, Oregon. KTVR-TV (channel 13) went on the air December 6, 1964, as a semi-satellite of KTVB, but had a La Grande studio at 1605 Adams Ave., producing a nightly newscast and other local programming. However, by 1967, the La Grande studio and office had been closed and KTVR was a total satellite of KTVB. KTVR was unique in the Pacific Time Zone because as a repeater of a Mountain Time Zone station, its "prime time" schedule was broadcast from 6 to 9 p.m. PT, two hours early. OEPBS (now Oregon Public Broadcasting) bought KTVR on August 31, 1976, and converted it to a non-commercial PBS member station on February 1, 1977.
