===WTCN-FM===
The 97.1 frequency was home to one of the first FM stations in the Twin Cities, [[sign-on|signing on]] the air in 1947 as '''WTCN-FM'''.<ref name="collections.mnhs.org">{{Cite web |url=http://collections.mnhs.org/visualresources/image.cfm?imageid=151085 |title=Archived copy |access-date=2010-06-28 |archive-date=2012-03-20 |archive-url=https://web.archive.org/web/20120320114656/http://collections.mnhs.org/visualresources/image.cfm?imageid=151085 |url-status=live }}</ref>  It was co-owned with WTCN (now [[WWTC]]), one of the oldest radio stations in Minneapolis-St. Paul, having signed on the air in 1925.

In 1949, [[WCCO-TV|WTCN-TV]] was launched on channel 4 with studios at Radio City Theater at 9th Street and LaSalle Avenue in downtown Minneapolis. WTCN's radio studios moved to the TV facility in September 1949, with WTCN-FM joining them by February 1950.<ref name="collections.mnhs.org"/>  All three stations were sold in 1952. The TV station was spun off to a new company, [[Midwest Radio and Television]], which also purchased a majority share of [[WCCO (AM)|WCCO Radio]] from [[CBS]] that same year. Midwest changed the call letters to match its newly acquired WCCO, while WTCN-TV was sold to the Minnesota Television Service Corporation headed by St. Paul businessman Robert Butler, a former ambassador to Cuba and Australia. Butler's company quickly applied for a new TV license on channel 11, but had to negotiate for the frequency with the owner of [[KMNV|WMIN]], who also applied for the channel. The two stations, WTCN and WMIN, arranged to share the TV broadcast day, alternating every two hours. This became the area's third TV station on September 1, 1953.  The WTCN call sign remained with it until 1985, when it became [[KARE (TV)|WUSA]].
