On August 15, 1944, WMOH signed on the air. Its founder and original owner/operator was Fort Hamilton Broadcasting. WMOH added an FM station in 1959, now Cumulus Media-owned 103.5 WGRR. Both stations went to separate ownership in the 1970s. In the 1950s and 1960s, WMOH maintained a full servicemiddle of the road format before switching to contemporary hits in the 1970s. Around the mid-1980s, the station moved to a mix of adult contemporary music, talk and sports, until it eliminated the music in the 1990s, switching to all-sports.
The station had been Cincinnati's affiliate for ESPN Radio until July 2007, when ESPN switched to WSAI. WMOH has since become more of a mixed news and sports talk station, featuring talk shows from Salem Radio Network, Audacy, Inc., and CBS Sports Radio. WMOH serves as the flagship radio station for Miami (Ohio) University athletics, and broadcasts local high school baseball, basketball, and football games. Since January 2008, WMOH has featured its own morning news and sports talks show, hosted by Chris Theiss and long-time WMOH employee Steve Vaughn.
