WTLZ retains a strong signal south of Saginaw toward Flint, but moving eastward toward the Lapeer County area, WSAQ 107.1 "Q Country" signal tends to overpower WTLZ as they are both on the same frequency.
107.1 FM signed on in October 1969 as WWWS "W3-Soul" with a ERP of 2,000 Watts. W3 Soul at the time played a mix of Jazz and R&B for the Tri-Cities. The studios were located on South Bancroft at East Genessee in Saginaw.
The station is the heritage African American-oriented radio station in the market and has featured some variation of urban format for decades.
In September 1988 the calls were changed to WTLZ as "Power 107" adding Disco, and Rap throughout the 1990s, then would evolve into a Rhythmic Contemporary Hit Radio format then totally as Mainstream Urban. It was around 1989 when the owners wanted to market WTLZ towards Flint and would increase the Power to 4,900 Watts, 107.1's signal would reach from North of Mt. Pleasant to southern Genesee County. WTLZ had some of the highest ratings ever in the 1990s with Specialty shows such as the "Saturday Night Street Mix".
In December 1998 WTL Broadcasting opted to sell the station to Connoisseur Communications which had already stations in Flint. In March 1999 Connoisseur tweaked WTLZ from Mainstream Urban to "Today's Best R&B and Jammin Oldies" "HOT 107", cutting back on (but not totally eliminating for several years afterward) rap and hip hop product from its playlist (though hip hop was played mostly at night). Eventually, the format evolved into the current Urban AC as most hip-hop was dropped from the playlist and the nighttime hip-hop programming was replaced by "slow jams" on the "Quiet Fire" (a variation of the Quiet Storm concept).
WTLZ was purchased by Cumulus Media who would sell their Saginaw stations to NextMedia Group in 2009. NextMedia rebranded WTLZ from Hot 107 to Kiss 107.1 in the fall of 2009, staying with its Urban AC format.
Kiss 107.1 is the Tri-Cities' outlet for the Steve Harvey morning show. Weekend programming includes Walt "Baby" Love's nationally syndicated Urban AC countdown, gospel programs on Sunday morning, and The Flow, Your Urban Jazz Connection, on Sunday afternoons.
NextMedia sold WTLZ and their 32 other radio stations to Digity, LLC for $85 million; the transaction was consummated on February 10, 2014.
Effective February 25, 2016, Digity, LLC and its 124 radio stations were acquired by Alpha Media for $264 million.
