WSBT (AM)

It is owned by Mid-West Family Broadcasting, with studios and offices on East Monroe Street in downtown South Bend.

[3] WSBT is the flagship station for University of Notre Dame football and men's basketball, as well as the South Bend Cubs.

[5] On June 29, 1922, the South Bend Tribune was issued a license for a new station on the shared 360 meter "entertainment" wavelength.

Because South Bend was the home of the Studebaker automobile company, it was suggested that "World's Greatest Automotive Zone" was an appropriate slogan based on these call letters.

On May 24, 1940, the Federal Communications Commission (FCC) announced the establishment, effective January 1, 1941, of an FM radio band operating on 40 channels spanning 42–50 MHz.

[20] However, W71SB's co-ownership with the Tribune resulted in a delay, after the FCC began an investigation as to whether newspaper ownership of radio stations should be restricted.

[23] On June 9, 1941, W71SB's construction permit was reinstated, pending the outcome of the newspaper ownership review,[24] and the station began broadcasting in May 1943.

In 1984, the station switched to locally programmed adult contemporary music, with the call letters becoming WNSN, as "Sunny 101.5".

[31] As network programming moved to TV, WSBT switched to a full service middle of the road format of popular music, news and sports.

On January 10, 1994, WSBT Radio debut a daily sports talk show with Tom Denin and John Fineran.

WSBT changes to a different directional pattern after sunset, resulting in marginal nighttime coverage outside St. Joseph County.
