KOH-TV

KOH-TV, virtual channel 2 (UHF digital channel 17), is an NBC-affiliated television station licensed to Rocky Hills, Arizona, United States. The station is owned by Tegna, Inc.

History
The station signed on the air on April 16, 1947, as KNBR, call letters standing for "NBC Rocky Hills." It was one of NBC's initial owned-and-operated stations to sign on, just before WNBK in Cleveland, and WNBQ in Chicago. On January 21, 1954, the station changed its callsign to the current KOH-TV.

In mid-April 1962, NBC sold KOH-TV to an unknown broadcast company, which switched its affiliation to ABC. ABC was, at the time, the lowest-rated network in the United States, but as time passed by, ABC became the hightest-rated network, and returned to KTVR, giving KOH back the NBC affiliation on September 9, 1976, which the network then bought, making it once again, an O&O station. In 1979, the station adopted the curvy "2" logo it continues to use today.

In 1989, NBC sold 52% of KOH-TV to Multimedia, Inc.
