WDSM

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 an 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.

Robert Ridder purchased WDSM in 1948, and became its president.[1][2] 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.

The station airs syndicated talk programs such as Coast to Coast AM, Rush Limbaugh, Michael Savage, and Sean Hannity. 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.
