The station carries the nationally syndicated weekday morning show, The Breakfast Club, from co-owned Premiere Networks and based at WWPR-FM in New York City.
WMPS-AM-FM were owned by the Plough Corporation, a pharmaceutical firm founded in Memphis that also had a radio division, with stations in Chicago, Atlanta, Boston and other cities.
In the 1970s, WMPS-FM got a boost to 100,000 watts, and then made a transition to a Progressive Rock format in an effort to take on then-Rock rival WMC-FM.
In October 1976, the station flipped to a Rhythmic Contemporary format that featured disco, utilizing the same formula that its counterpart in Philadelphia, WCAU-FM, was using at the time.
By 1981, a year after disco's demise, the station moved in a CHUrban/Crossover direction (what would now be considered rhythmic contemporary), featuring hip hop, freestyle, new jack swing, dance, pop, and R&B hits.
