The station launched in 1967 as WDUZ-FM (a sister station to WDUZ) and aired a beautiful music format until January 1990. At that time, the station shifted to a light adult contemporary format as "New Light 98.5 WQLH" (meaning "Quality Light Hits"). The format would evolve into a more modern (and more upbeat) adult contemporary playlist by the mid 1990s, eventually adopting the "Star 98" branding in 1999, the year the station was purchased by Cumulus Media. Star 98 begins a "Totally 80's Weekend" Friday at 5pm. They are known for playing "30 minutes commercial free" music, as well as an "All 80's Lunch".
Steve Davis & Laura McKenna comprise the morning show, which airs Monday through Friday from 5:30am to 9:00am(CST). Bill Rabeor provides the news during the morning show. Stix Franklin is the mid-day host and Jimmy Clark hosts the afternoon drive. Backtrax USA & The Amazing 80's are syndicated shows that air during the Totally 80's Weekend programming. Ron Stevens and Scottie Stick are also on the weekend line-up.
Cumulus swapped WQLH and four other Green Bay stations to Clear Channel in 2009 in exchange for two Cincinnati radio stations; however, Cumulus continued to operate the stations. In August 2013, Clear Channel reached a deal to sell the five stations back to Cumulus.
