About KAAL ABC6The station went on the air as KMMT on August 17, 1953, and broadcast an analog signal on VHF channel 6. Local merchants Martin Busted, Harry Smith, and Palmer Ulland, who also owned KAUS radio, were its founding owners (AM 1480 and FM 99.9). The station was formerly a major CBS affiliate with secondary ABC and DuMont affiliations. Following the establishment of KGLO-TV (channel 3, now KIMT) from Mason City in late 1954, KMMT changed its principal allegiance to ABC. DuMont was subsequently eliminated once the network went out of business in 1956. This station is the Upper Midwest's longest-running ABC affiliate.
The station was also temporarily linked with the NTA Film Network in the late 1950s. It shared studios with KAUS radio on MN 105 in Austin, where both stations are still broadcasting today. The Family Hour, hosted by Christian Pastor Joe Matt, was one of the few local programs produced by the television station. The programme aired until April 2001 and was one of the country's longest-running, domestically produced religious broadcasts.
