About KXMB TVKXMB first went on the air on November 19, 1955 as KBMB-TV, owned by Fargo businessman John Boler and his North Dakota Broadcasting Company. The station had a primary affiliation with CBS, but carried other networks as well. During the late 1950s, the station was briefly affiliated with the NTA Film Network. In 1958, it moved to its current location.
In 1959, Boler sold a part-interest in the North Dakota Broadcasting Company to Chester Reiten of Minot. The two men teamed up to buy that city's CBS station, KCJB-TV, and changed the calls to KXMC-TV. The two stations merged their operations, with KXMC as the flagship station. In 1959, KBMB changed its calls to the current KXMB. They would put KXMD-TV in Williston on in 1969.
