The End of Oldies: 104.3 WJMK Chicago | March 2, 2005
Here’s a recording of WJMK “in transition” from “Oldies” to “Variety Hits”. The actual format change wouldn’t come for three more months, but apparently what we have here, is an aircheck of the day WJMK dropped the term Oldies and just went with the call letters. This was the start of a new jingle package reflecting that.
Three months later, “Jack” would arrive and turn the market on its ear. Listeners hated it, much like they did in New York City, when WCBS-FM dumped Oldies for Jack’s Variety Hits. But that’s for a later story.
