About KXMB TVKXMB debuted on the air as KBMB-TV on November 19, 1955, owned by Fargo industrialist John Boler and his North Dakota Broadcasting Company. The station was mostly affiliated with CBS, but it also broadcast from other networks. The station was temporarily linked with the NTA Film Network in the late 1950s. It relocated to its current location in 1958.
Boler sold a stake in the North Dakota Broadcasting Company to Chester Reiten of Minot in 1959. The two individuals joined together to purchase the city's CBS station, KCJB-TV, and rename it KXMC-TV. The two stations combined their operations, with KXMC serving as the flagship. KBMB's call letters were changed to the present KXMB in 1959. In 1969, KXMD-TV in Williston would go on the air.
