WCBS-FM is expected to switch back to oldies next week, if this article in the New York Daily News is any indication. This rights a wrong made two years ago when it dumped the longtime oldies format for the adult hits format known as Jack-FM. Ratings for WCBS-FM dropped like a rock and has not recovered.
WCBS-FM became an oldies 35 years ago yesterday, on July 7, 1972.
It’s not likely that WJMK-FM will make a similar move in Chicago, since the Jack format here has been slightly more successful, plus ABC saw a hole and filled it when it launched the True Oldies Channel at WZZN-FM, replacing the alternative rock format on September 26, 2005.
WJMK-FM flipped to Jack the same day WCBS-FM did on June 3, 2005.
