The station is owned by Townsquare Media. It formerly broadcast as "Arrow", on the same frequencies and with a similar format, but using call letters WXBB and WXBP. The change to the new name and call was made in March 2000. Citadel Broadcasting acquired the station in August 1999 when it purchased Fuller-Jeffrey Broadcasting Companies. Citadel merged with Cumulus Media on September 16, 2011.
On August 30, 2013, a deal was announced in which Townsquare Media would acquire 53 Cumulus stations, including WSAK/WSHK, for $238 million. The deal is part of Cumulus' acquisition of Dial Global; Townsquare and Dial Global are both controlled by Oaktree Capital Management. The sale to Townsquare was completed on November 14, 2013.
