In June 1989, WLS announced it was going all-talk by the end of the summer. Rumors were that the change was to happen September 1. Air personalities were becoming more talk intensive anyway and midday talk was added as well. But quietly, with no warning, on August 23, 1989, at 7 P.M., WLS stopped playing music altogether. Phil Duncan was the last DJ to play music on WLS, and as Duncan finished up his show, a voice in the back of the studio (that of then-WYTZ worker Steven Craig) was heard saying "Goodnight!" (Craig unknowingly (and unofficially) became the last live voice on Musicradio WLS.) Appropriately, the last song was "Just You 'n' Me" by Chicago. WLS then became a talk station, with Sally Jesse Raphael as its first host. In the beginning of the talk format, WLS featured high-rated talk talents from around the country, such as Bob Lassiter from Tampa Bay, Stacy Taylor from San Diego and the station's biggest hit, Rush Limbaugh out of New York. After a few years, however, Lassiter, Taylor and some of their other national hosts were dropped in favor of more local hosts. Jay Marvin also had several stints on WLS, where he was one of the few liberal voices on its political talk shows, which had mostly conservative viewpoints. The station iserved as the "flagship" broadcast outlet for the Sunday night, national political talk show, "Beyond the Beltway with Bruce DuMont".
