The station was launched and owned by the Hiawathaland Broadcasting Company, who later shifted the station to a middle of the road format in the late 1960s, prior to selling the station to Patterson Communications (later the Miami County Broadcasting Company) in 1971, as owned by Richard E. Hunt, who also owned WCBY AM & -FM in Cheboygan and WPTW AM & -FM in his hometown of Piqua, Ohio.

WSOO was purchased by Fabiano-Strickler Communications in 1981, who shifted to its current adult contemporary/talk format in 1989.

Live sports coverage on WSOO includes Detroit Red Wings, Detroit Tigers, and Sault High Blue Devils games, as well as the regional high school sports talk show Coach's Corner, and annual coverage of the International 500 snowmobile race in Sault Ste.

Local on-air personalities at WSOO include morning host Allan Gibbs, DJ/news anchor John Bell, sports anchor Mark SanAngelo, chief meteorologist Karl Bohnak, and Sault High Blue Devils play-by-play announcer & Coach's Corner host Dave Watson.
