WRKS incorporated artists such as Kurtis Blow, Whodini, Run DMC, Fat Boys, LL Cool J, and Public Enemy into the same rotation as such established acts as Ashford & Simpson, Kool and the Gang, and Gladys Knight. In 1986, Indianapolis-based Emmis Communications launched WQHT (then at 103.5 FM), which had an early emphasis on dance music, forcing WRKS and WBLS to add more dance music to their playlists again. In 1988, Mayo left to organize a new broadcasting company with Lee S. Simonson and Bill Pearson, and RKO appointed Charles Warfield (former general manager of WBLS) as the new General Manager of WRKS. With Vinny Brown as the stations Program Director WRKS (98.7 Kiss Fm) became the #1 Radio Station in the largest media market in the world for six years right through the mid 1990s.
