The station, under the WMRV call sign, was named for the late entertainer and game show creator Merv Griffin, who owned the FM station, as well as its sister station, WENE. When Griffin and his wife, Julann, divorced in 1973, she retained ownership of the stations as part of the settlement. The station was a Top 40 station from its beginning until 2004 when it was flipped to Hot AC. In April 2012, the station was flipped back to Top 40. All personalities on the station at the time were either moved or let go, and replaced my out-of market personalities, with the exception of the afternoon timeslot. On March 11, 2013, WMRV-FM rebranded as "Now 105.7" under new call letters, WBNW-FM.
