Known to radio listeners as MC Marcus Chapman, the author of the explosive tell-all book "Sex Time And Radio: The Raw Uncut Story of an On-Air Personality and the Decline of the Radio Industry" was born and raised on Chicago's south east side. He began his radio career in 1992 at WKDI in DeKalb, Illinois while attending Northern Illinois University. Upon graduating in 1995 with a Bachelors of Arts Degree and a minor in Black Studies, Chapman became the youngest employee at Chicago's #1 radio station at that time, WGCI. After serving time as a studio assistant and show producer, he joined the staff of on-air personalities in 1996; a staff that produced nationally renowned alumni like Tom Joyner, Doug Banks, Steve Harvey, and BET voiceover talent Rick Party. Marcus also worked alongside such Chicago radio talents as First Lady, Ramonski Luv, Dr. Luv, Jeanne Sparrow, Sam Sylk, and the Bad Boyz. In 1997 Chapman began building a significant following through his Friday night/Saturday morning show called "The Afterset", and made himself memorable to listeners by using the sound bite of legendary actress Eartha Kitt saying "Marcus darling" from the Eddie Murphy film Boomerang.
