The stationsigned on the air on September 20, 1968; 57 years ago (1968-09-20). The originalcall sign was KACO, and it was owned by the Apollo Broadcasting Company.[2] It aired anadult contemporary (AC) andmiddle of the road (MOR) format. A fire at the transmitter took the stationoff the air in January 1970.
Two months later, the station returned to the air, changed its call letters to KGRV, and relaunched as "Music for Groovy Adults," offering a more upbeat AC format. This lasted until 1972, when it once again changed call letters, this time to KKSS, and rebranded as "Kiss 108". By 1974, KKSS switched tocountry music. A year later, KKSS flipped to anR&B format, dubbed "Black in Stereo". In February 1979, KKSS altered its R&B format and adopted the moniker "Studio 108," with a hybriddisco music and R&B format, competing with WZEN (nowKATZ-FM).
In June 1979, the call sign was changed to KMJM and rebranded as"The New Majic 108 FM, Where the Music is the Majic!". KMJM Was catered to both African-American and Caucasian-American listeners as the St. Louismarket's first "CHUrban" station (a forerunner to theRhythmic Contemporary format). At the time, the station was owned by Keymarket Communications. KMJM was ranked among the top five stations in the St. LouisArbitron ratings during the 1980's, as it shifted towards a mainstreamUC direction.
In May 1988, KMJM was sold to Noble Communications ofSan Diego for $19 million. KMJM's FM signal was one of the best in the St. Louis area, as the station emerged as the top urban station in the market.Jacor bought the station in 1997.
On October 20, 1997, at midnight, after 18 years on 107.7 FM, KMJM was moved to recently purchased sister stationWCBW (104.9 FM), which aired aChristian music format.[3][4] After a 12-hourstunt with a looped heartbeat and announcements redirecting KMJM listeners to the new frequency and the launch of a new format on 107.7 later that day, KSLZ and its current top 40/CHR format, branded as "Z107-7", debuted. The flip was to fill a format hole left byWKBQ, who dropped the format formodern AC on January 24 of that year. The final song on "Majic" was "Good Girls" byJoe, while the first song on "Z" was "Get Ready For This" by2 Unlimited.[5]
At first, KSLZ was the St. Louis affiliate for theMJ Morning Show, based atTampa sister stationWFLZ, and the only affiliate for the show outside of the Eastern Time Zone. After the show ended in February 2012, KSLZ became the St. Louis affiliate forThe Bobby Bones Show. After Bones relaunched his show to air oncountry stations in February 2013, KSLZ replaced him withElvis Duran and the Morning Show.[6] In December 2017, KSLZ dropped Duran for local host Jordan DeSocio.[7] As part of company-wide layoffs, DeSocio exited the station in November 2020, and was replaced by "The Jubal Show", based atSeattle sister stationKBKS.[8]
KSLZ made the conversion toHD Radio in 2006. 107.7-HD2 initially carried a New CHR format branded as "Z107-7 Amped." On June 22, 2016, KSLZ-HD2 switched to "Pride Radio".[9]
