I was spinning the radio dial the other day and heard some rock/pop on what I thought was Oldies 104.3. I stayed tuned and heard that it's now "Jack FM." They still have the same call letters (WJMK), but it's a completely new format. They seem to have gotten rid of live DJs. You know, like an iPod plugged into a giant antenna. Their website seems to still refer to the oldies version. I miss their jingle already.
Edit: I found some news stories about this. Chicago Tribune business news, Sun Times opinion piece. The Trib article makes references to the iPod-like programming. I swear I didn't read that before I made this post. I guess it happened a few weeks ago. "...By burying the story over the weekend, they hope to minimize criticism from the press and outcry from the public. That no doubt figured into the timing of Infinity Broadcasting, which waited until 4 p.m. Friday (June 3) to blow up two of its heritage oldies stations." Stupid bottom-line mentality.
One more story with a great quote from the man responsible:
"My job in leading the company -- for better or worse -- is to make every radio station as profitable as it can be," he said.
"People want to put their goddam foot on your neck whenever you make a change. The problem is that there's a lot of people who don't have the balls to make a change. OK? We're on the offense. We're not on the defense. OK? We might have made a mistake. Right now, I don't think we made a mistake."
