Sky Daniels was the original Program Director and Afternoon Drive host. Daniels hired several Chicago legendary air personalities, including Mitch Michaels, Johhny Mars, and more. Billboard Magazine named NINE-FM 'Top 40 Radio Station Of The Year' in 2004. He left in 2005 and was replaced by Matt DuBiel. Initially Nine FM was not restricted to any content format, but after DuBiel became director, the playlist was tightened because of low ratings and less songs were played.^[1]

On May 19, 2006, Nine FM started airing Dance Factory FM on Saturday nights, which expanded to Friday nights after August 12, 2006.
