Update 11/30: Midwest Family has applied to change the calls of WTDY and WTDY-FM to WOZN and WOZN-FM respectively. Concurrently the following domains have been registered pretty much confirming the stations will flip to Sports after the holidays: 1067WOZN.com, 1670WOZN.com, 1670TheZone.com, and MadCitySportsZone.com.
Original Report 11/21: Midwest Family Broadcasting’s 1670 WTDY/106.7 WTDY-FM Madison has dropped its News/Talk format and is stunting with Christmas music.
WISC-TV reports that the entire local airstaff for the station has been dismissed including morning host John “Sly” Sylvester and 7 or 8 others. The stations will debut a new format after the holidays, which will likely be the new CBS Sports Radio network.
1670 WTDY added the FM simulcast on what was 106.7 WWQN in December 2011. In addition to WTDY and WTDY-FM, Midwest Family owns Rhythmic CHR “93.1 Jamz” WJQM, Rock 94.1 WJJO, AC “Magic 98” 98.1 WMGN, Country “Q106.3” WWQM, Spanish CHR “La Movida 1480” WLMV, and Oldies “Hitradio 1550” WHIT in the Madison market.

Not sure that sports is the right answer, but the talk format should have been dropped YEARS ago. It’s never been a winner in the ratings.
Keeping the farm reports is baffling to me. That programming element does not really mesh with sports/talk. Maybe I’m wrong, but what about the possibility of WTDY going to classic country or some version thereof?
The farm reports air on sister WWQM, and it’s also a networked show across the state.
