KXFN began broadcasting in 1927 as KWK. KWK was the Mutual Broadcasting System affiliate in St. Louis for most of its existence until August 1969, when the station switched from standards to an R&B format.
KWK's claim to national fame was a film clip where a disc jockey at the station is seen smashing one of Elvis Presley's records and declaring "rock and roll has got to go!"--a clear sign that KWK had veered away from the rock format. This clip can be seen in the 1981 film "This Is Elvis".
In 1973, the station went off the air until late-1978, when it returned as a Top 40 station, and in March 1979, it began simulcasting with WWWK-FM (106.5). The two stations kept simulcasting until KWK became KGLD (an oldies station) in June 1984. On January 1, 1992, KGLD changed to all-sports KASP. The station went back to simulcasting with 106.5 FM (which had since become WKBQ-FM) in 1993. After eleven years of using various formats, including Gospel music, KSLG switched back to sports in 2004.
On July 1, 2010, Grand Slam Sports, owner of fellow St. Louis sports station KFNS, announced its intention to purchase KSLG pending FCC approval and that it would begin managing the station immediately under a local marketing agreement. This resulted in the return of The Jim Rome Show to the St. Louis market after an absence of approximately a year.
On June 20, 2012, KSLG changed their call letters to KXFN.
On March 10, 2014, KXFN changed their format to sports, with programming from Yahoo! Sports Radio.
On April 1, 2014, KXFN changed their format to talk/sports, branded as "1380 The X, Xtreme Talk Radio". Remaining staff from KFNS was shifted to KXFN.
On October 1, 2014, KXFN changed to a music/talk station with multiple styles of shows, offering music of different genres and comedy talk content.
On March 16, 2015, KXFN changed back to a sports and talk format through an airtime lease with talkstl.com. They feature programming from Yahoo! Sports Radio as well as some local talent such as Kevin Slaten. The Jim Rome Show was added by April 2015.
On December 19, 2015 KXFN went silent.
