In early 1985, Urban WDAO moved to AM, and 107.7 switched to an Adult Contemporary format as Star 107.7/WWSN under owner Stoner Broadcasting. This format would last until 1991, when the station switched to Hot AC under Vice President/General Manager Deborah Parenti (who oversaw the switchover of the call letters from WWSN to WMMX) and Randy James as Mix 107.7/WMMX. In 1993, Bob Sweeney became the new Morning Show host, replacing "The Tall Guys". He would serve as morning host along with co-host Kristi Leigh until 2005, when he moved to Smooth Jazz 106.5 WDSJ as Morning Show host, and would be replaced by PD Jeff Stevens. The station would be sold by Stoner Broadcasting to American Radio Systems in 1995, and in turn Jacor would purchase the station in 1998, and later be merged with Clear Channel Communications eventually taking over the station. In the late 1990s, the station would take a 1980s-lean, as the 1980s Oldies format became popular during this period, and the station would air a 1980s Oldies format during the weekends called "The Time Warp Weekend". Upon his move from sister Alternative WXEG 103.9 The X in the Summer of 1998, new PD Jeff Stevens would not only replace midday host Kate Burdett, who moved on to other stations in the Dayton cluster, but also add a specialty show to the line-up entitled The Time Warp Cafe from Noon-1 PM, spotlighting music from the 1980s and adding in a "Vault" song, which is a song that reached cult status in the 80s or received a lot of play via music video on MTV but never hit big on the charts. The first song played 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 90s that featured an 80s artist. The very first title played was "So Close" by Daryl Hall and John Oates from 1990. It was later retitled "A Taste of the 90s" to broaden the selection of titles that could be played. 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" and remain named that to this day. The 80s lean also continues, including the rebroadcast of Casey Kasem's American Top 40 countdowns Saturday mornings from 6 AM to 10 AM, which feature originally aired broadcasts from 1980-1988. WMMX has been airing the rebroadcasts of AT40 since 2001 when they were packed as "AT40 Flashback", at which time the shows were condensed three hour rebroadcasts of AT40, usually beginning the countdowns around #30. This was due to Premiere Radio Networks believing that songs between #40-#31 would be too unknown for the target audience to remember, which could cause listeners to tune out due to the unfamiliarity with said songs. When Premiere Radio Networks canceled the program, WMMX continued to rerun the package until they were replaced by an all-new rebroadcast package from Premiere Radio Networks branded as "Casey Kasem's American Top 40: The '80s" in April 2007, which would broadcast the shows in their original, four hour format.
