WTBC-FM (100.3 MHz) is a radio station licensed to Chicago, Illinois, with a rhythmic adult hits format, focusing on music between 1990 to 2015. The station is owned by Hubbard Broadcasting, Its studios are located at One Prudential Plaza, with transmitter facilities atop the John Hancock Center downtown.
The station has had multiple owners since coming on the air in 1948, but has usually carried lighter music depending on industry trends, never veering too far towards any type of hard rock or rap format and specifically programmed to appeal to office listeners, and since 1997, additionally has been structured playlist-wise to avoid any competition with its higher-rated sister station WTMX.
