The Station signed on as a Urban Contemporary format in 1996 as "Smokin 99.1." The station covers Elkhart, South Bend, Benton Harbor & Michigan City. This was the second Urban station in the Southwest Michigan area, the first having been the former WLLJ-AM 910 in Cassopolis which by then had switched to oldies as WGTO. The studios were located in Niles.
On February 4, 2005, WYPW formerly adult contemporary WLRX became "Power 95.7" which put "Smokin 99" in direct competition for the Urban and Hip Hop format. In 2006 WSMK decided to tweak the format to a Rhythmic Adult Contemporary approach and became "Movin 99.1, Michana's Greatest Hits", with the format delivered via satellite from Waitt Radio Networks.
As of October 2010, with WYPW changing to Classic Rock as WAOR, which was at 95.3, 99.1 has transitioned back to locally originating programming and brought back the "Smokin' 99.1" positioner. Per the station's web site they feature a CHR/Rhythmic format featuring such artists as Beyoncé, Usher, Jay-Z, Katy Perry, Lady Gaga, Eminem, Rihanna and Nicki Minaj.
