About KAAL ABC6The station signed on the air on August 17, 1953 as KMMT and aired an analog signal on VHF channel 6. Its first owners were local businessmen Martin Busted, Harry Smith, and Palmer Ulland, who also owned KAUS radio (AM 1480 and FM 99.9). Originally, the station was a primary CBS affiliate with secondary ABC and DuMont relations. After KGLO-TV (channel 3, now KIMT) launched from Mason City in late 1954, KMMT switched its primary affiliation to ABC. DuMont would eventually be dropped in 1956 after that network shut down operations. This station is the longest-tenured ABC affiliate in the Upper Midwest.
During the late-1950s, the station was also briefly affiliated with the NTA Film Network. It shared studios with KAUS radio on MN 105 in Austin where the two radio stations continue to operate today. The television station produced a few local programs most notably The Family Hour hosted by Christian Pastor Joe Matt. The program aired until April 2001 and was one of the longest-running, locally produced religious shows in the United States.
