The station previously aired adult contemporary and easy listening formats prior to switching to oldies music, initially concentrating on 50s and 60s music (as "Oldies 94.9") and transitioning over time to its current Classic Hits approach (under the simple "94.9 WOLX" branding). WOLX is noted in Madison for airing all-Christmas music, usually from Thanksgiving to Christmas, although the station has started playing holiday music as early as November 5 (doing so in 2009). Christmas music started on November 25th in 2014.
On-air personalities on WOLX include Scott Miller, who joined WOLX as its morning host on November 9, 2010. A major feature of Scott Miller's show is the Brain Strain, a difficult trivia question, at 7:30am weekdays. WOLX Program Director David Moore is the midday talent, Jim McGaw hosts afternoons and Jason Ryan is on from 7pm-12m weeknights. Syndicated host Tom Kent is on 7pm-12m Saturday with the Ultimate Party and his 70s Show airs 6pm-11pm Sundays. The Beatle Brunch is a one-hour program hosted by Joe Johnson with music and conversation about the the Beatles. WOLX airs Super 70s Weekends regularly, in which all the music played is from the 70s.
