 On December 6, 2007, WBZZ changed its Hot AC format (which violated Regent-Clear Channel's non-compete agreement; WRVE also had a Hot AC format) to Mainstream adult contemporary.The call letters and the name "Buzz 105.7" remained.While most of the jingles and imaging initially stayed from the previous format, WBZZ began airing new jingles in January 2008, better suited for an Adult Contemporary station.
