History

WDAO-FM and WWSN
The station signed on the air in .  Its original call sign was WDAO-FM.  It simulcast its AM sister station WDAO 1210 AM, an R&B outlet serving Dayton's African American community.  At the time WDAO was a daytimer.  So WDAO-FM was able to continue its programming after dark, when the AM station was required to go off the air.  In the 1970s, the AM station switched to a talk radio format, while WDAO-FM remained an R&B station, calling itself "Ohio's Stereo Soul Giant."

In early 1985, WDAO-FM's urban contemporary format moved to 1210 AM, while 107.7 FM switched to adult contemporary music.  It was known as "Star 107.7" WWSN under owner Stoner Broadcasting.  This format lasted six years.

WMMX
In 1991, the station switched to hot adult contemporary under Vice President/General Manager Deborah Parenti.  She oversaw the switch of call letters from WWSN to WMMX.  That call sign stood for the new moniker, "Mix 107.7."

In 1993, Bob Sweeney became WMMX's new morning show host, replacing morning team "The Tall Guys".  His co-host was Kristi Leigh until 2005, when he moved to "Smooth Jazz 106.5 WDSJ" as morning show host.  Sweeney was replaced on Mix 107.7 by PD Jeff Stevens.

Stoner Broadcasting sold WMMX to American Radio Systems in 1995, and in turn Jacor purchased the station in 1998.  Jacor later merged with Clear Channel Communications.  In 2014, Clear Channel switched its name to the current iHeartMedia, Inc.

1980s hits
In the late 1990s, the station focused on 1980s hits along with current and recent Hot AC titles.  On weekends, the station switched to all 1980s songs.  This was known as "The Time Warp Weekend".  Upon his move from co-owned Alternative Rock "WXEG 103.9 The X" in the Summer of 1998, PD Jeff Stevens replaced midday host Kate Burdett, who moved on to other stations in the Dayton cluster.

He also added a specialty show to the weekday line-up, "The Time Warp Cafe" from Noon-1 PM.  It spotlighted music from the 1980s and adding in a "Vault" song, which reached cult status in the 1980s or was frequently played on MTV. The first song heard during this segment was "Don't Pay The Ferryman" by Chris DeBurgh.  A few years later, a "Sounds like the 80s" song was added, which was a song from the early 1990s that featured a 1980s artist. The first title played was "So Close" by Daryl Hall and John Oates from 1990.  The feature was later renamed "A Taste of the 90s" to broaden the selection of titles that could be played.

Whatever Weekend and American Top 40
In 2006, the "Time Warp Weekend" was replaced by "The Whatever Weekend", in response to the growing popularity of adult hits stations across the country. In early 2010, weekends were renamed "The Weekend Mix." The 1980s focus also continued, including the airing of classic episodes of American Top 40 with Casey Kasem.  They were heard Saturday mornings from 6 to 10.

WMMX has been airing the rebroadcasts of AT40 since 2001 when they were called "AT40 Flashback."  The shows were condensed three-hour rebroadcasts of AT40, usually beginning the countdowns around #30. This was due to syndicator Premiere Networks believing that songs between #40-#31 would be too unknown for the target audience to remember. When Premiere canceled the program, WMMX continued to rerun the package until they were replaced by an all-new rebroadcast package from Premiere, branded as "Casey Kasem's American Top 40: The '80s."  They started airing in April 2007.  The shows are broadcast in their original, four-hour format.
