The radio business changed in the five and a half years since Washington-area DJ Donnie Simpson (pictured left with Radio One SVP of Programming Jay Stevens) was last on the air. He started on the air at age 15 in Detroit. Now doing afternoon drive at Radio One's WMMJ(FM), Washington, Simpson spoke at Nielsen's Client Conference Thursday. He said, Jocks today are constrained. I used to go to my room and pull records. I still do that. Jocks don't get a chance to be jocks. Talent can't breathe now. They've been suppressed and have something like 10 seconds to speak. "Let my people go!" he pleaded with programmers.
