The station is owned by Green Bay-based Starboard Broadcasting and airs Starboard's Relevant Radio network.The station originally signed on as WKAU-AM in a Top 40 format. In 1984, the station was sold to Quinn Martin of Milwaukee who changed the call letters to his initials, WQWM-AM, and made it an oldies music format. The station changed hands again in 1993 to a new ownership who changed the calls to WSGC and the format to "Positive Country" music. Another sale in 1999 resulted in the station becoming all-sports "1050 The Jock, WJOK," which carried programming from the national Sports Fan Radio Network as well as local broadcasts of Wisconsin Timber Rattlers baseball. WJOK was purchased by Starboard Broadcasting in 2000, and the station joined Starboard's Relevant Radio network on November 26 of that year.
