History Easy Listening, Country and Classic Rock The station signed on the air on . Its original call sign was WMNI-FM, the FM counterpart to WMNI 920 AM. The two stations mostly simulcast an easy listening format. By 1978 the station's call letters were WRMZ and, in the early '80s, it started to broadcast a country music format. From 1987 to 1992, the station was known as WMGG, Magic 99-7, and played classic rock. The Blitz: 1992–2008 The Blitz began at 4 p.m. on July 2, 1992. WBZX aired an active rock format. In morning drive time, it carried The Howard Stern Show, syndicated from New York City from 1997 to 2005. The Rock: 2008–10 On April 3, 2008, WBZX began stunting with radio static and a voice mentioning that the "station is rebooting". The last song played on The Blitz was Breaking Benjamin's "Until the End". The next day, at 5:00 P.M., WBZX relaunched as The Rock, along with the call letters changing to WRKZ. The new station premiered with Nirvana's "Smells Like Teen Spirit". The Rock still had the active rock format, but it focused less on new music and played popular rock music from the 1980s. The station added the syndicated The Bob & Tom Show during the Morning Drive in December 2008. During the last few months as The Rock, the station added rock songs from the '60s and '70s into its playlist, shifting it into a Mainstream Rock direction. Only a few months later, the station hosted its first-ever "Town Hall Meeting", with Program Director Hal Fish and on-air personalities Ronni Hunter and Blazor taking calls, emails and texts as to what Columbus area listeners wanted more and less of on 99.7. A week later, on April 1, 2010, they once again went to the airwaves and detailed an "Action Plan" as to what would happen on the station in the following weeks, including the return of such Blitz-era staples
