On April 26, 1958; 66 years ago (1958-04-26), WMNI first signed on the air. For most of its three decades, it had a full service, country radio format. As country music listening started to move from AM to FM in the 1980s, WMNI switched to a satellite-delivered adult standards format from Westwood One. By the late 1990s, much of the music was locally programmed using Columbus-based disc jockeys. As of August 2007, WMNI shifted back to Westwood One's "America's Best Music" format, a mix of soft oldies and standards.
On June 14, 2012 at 6:00 a.m., WMNI switched to a simulcast of WMNI-FM, which had flipped from a classic hits sound as WTDA-FM to a news format.
On July 18, 2013, the AM/FM simulcast ended, with WMNI returning to the soft oldies and adult standards format.
On June 12, 2017, WMNI changed their format from adult standards to soft adult contemporary music, branded as "Easy 95.1 & 920" (simulcast on FM translator W236CZ 95.1 FM Columbus).[4]
On June 14, 2022, WMNI changed their format from soft adult contemporary to sports, branded as "Fox Sports 920", with programming from Fox Sports Radio. The 95.1 translator switched to a relay of sister station WJKR's HD2 subchannel.[5]
