WMMO is a Cox Radio station in Orlando, Florida, broadcasting at 98.9 FM with an Adult Hits format. The station signed on as WEZO in 1990 before taking its current callsign. Previous owners of this station include Infinity Broadcasting, Granum Communications, and Radio Orlando L.P., a partnership controlled by Jim Martin.  WMMO is known for its pioneering format, Rock AC, that blended elements of adult contemporary, adult alternative and album rock radio. Its creators sought to bring back a listening experience similar to early FM rock stations of the late 60s and 70s, focusing on music rather than contests and promotions. A popular slogan in its early days was, if you want to win money, play the lottery. WMMO used a wide ranging playlist of songs from many genres, and its library stretched from the mid 60s to the present day, unlike many stations of its time that focused on small slices of music from specific genres. WMMO also made a promise to always identify songs by title and artist frequently, and to never talk over the music as it played, as many Top 40 stations and DJs like to do. We love the music as much as you do was another slogan pioneered by WMMO that has been copied widely in the radio industry ever since.

90 days after signing on, WMMO was ranked number one in adult listeners in the Orlando market, and was among the ratings leaders in Orlando for its first four years. In the mid 90s, management changed and the station shifted to a more aggressive playlist of new progressive music. Ratings fell dramatically until, in 1996, Cox Radio took over and, for the most part, returned the format to its original Rock AC roots. WMMO has regained its leading position in the market ever since.

In 2008, longtime personalities Jerry Steffen and Jay Francisco were let go. Steffen was at WMMO for 18 years and Francisco for 14 years.
