Since Mid-July, BJ and his crew on KISW have changed the format of the show to include more Classic Gold tracks. BJ's playing 3-4 songs per hour, just like a lot of shows instead of being exclusively a talk show as in the past 11 years of his program.
Entercom knew Bob's deal was up and have been counter-programming KZOK's music in Morning Drive and the Midday shifts on KISW by playing more classic gold tracks in Morning Drive for 3 months now. The midday has had more classic rock tracks since Ricker's departure.
I believe, Entercom wants KISW to re-enter the genre of Classic Rock and lean away from the newer and current bands of today to protect KNDD's musical direction.
Here's the big deal. In April 2011, BJ and his crew vacate KISW's Morning Drive shift and move down the dial to KNDD while Bob and his crew return to KISW. KISW also goes straight forward into KZOK's music selection.
