WLS-FM (94.7 FM) is a Chicago classic hits radio station. The station was founded by ABC, and was sold (along with the rest of ABC's non-Radio Disney and ESPN Radio stations) by Disney to Citadel Broadcasting in 2007; it is now owned by Cumulus Media, following its 2011 merger with Citadel. WLS-FM broadcasts from studios (shared with former television partner WLS-TV) located on North State Street in the Chicago Loop, and its transmitter antenna is located atop the Willis Tower.
