WDSM (710 AM) is a talk radio station in Duluth, Minnesota, (licensed to Superior, Wisconsin). WDSM was created in 1938 as an affiliate of the Mutual Broadcasting System. The requested call letters were W Duluth Superior Mutual. WDSM provided Mutual programming throughout the Iron Range of Northern Minnesota as well as the Duluth-Superior market. WDSM switched network affiliations with NBC powerhouse WEBC in 1955. This was a direct result of WDSM's commitment to television and its founding of WDSM Channel 6 on March 1, 1954 as a NBC affiliate. WDSM stayed with NBC Radio until the early 1990s. The station aired a country format during the 1980s, and then sports radio during the 1990s.
WDSM is owned by Midwest Communications, which also owns KDKE, WDUL, KDAL, KTCO, and KDAL-FM in Duluth. All the Duluth stations share the same studio location at 11 East Superior St. Suite 380, downtown Duluth.
In perhaps a throwback to the station's sports radio days, WDSM still serves as the official Green Bay Packers station for the Duluth/Superior area.
