WMLW also carried Milwaukee Brewers baseball games and aired syndicated programming such as The Rockin' America Top 30 Countdown with Scott Shannon and Westwood One's That's Love in the 1980s.

In 1989, with a change in ownership to Joyner Communications, the station flipped to Top 40 hits as 94.1 WTFX "The Fox".

On Monday, November 3, 2008, Bair returned to WJJO to co-host the morning show for another eleven years.

In June 2013, Michele Clark's Sunset Sessions convention awarded WJJO the "rock station that plays the most new music".
