WZIM (Classic Hits 99.5) is a radio station serving the Bloomington-Normal, Illinois. The station airs a classic hits format. The station signed on in late 2001 as WCSO, with the call letters quickly changing to WDQZ. It was a Classic Hits simulcast with WDQX in Peoria. In December 2005 WDQX was sold, and the simulcast with WDQZ was split. Since then the station has evolved into a more straight-ahead Classic Rock station. In September 2009 WDQZ stunted as an all TV theme station for a day and a half. On September 18, 2009 WDQZ changed back to a classic hits format.
