Afternoon drive personality Big John Howell has exited Cumulus Media’s news/talk WLS-AM, Chicago after more than 10 years with the station. WLS posted the following to Facebook: “Yesterday was John Howell’s last show on The Big 89. He has been a staple of 890 WLS for over a decade. His wit, political prowess, and focus on Chicago conversations has given our audience a destination for smart, local radio in the afternoons. Thank you, John, for being a part of the fabric of The Big 89.” Howell has not commented publicly on his departure from the station.
