How "rap" started: In the beginning, the DJ was the most prominent person in the rap music equation, but once the music industry saw dollar signs in the creative efforts of MCs, or masters of ceremonies, such as "Love Bug" Starski and Kurtis Blow, the MCs were termed as "rappers," and the music was labeled "rap." Soon, in the eyes of the public, rapping eclipsed the art of DJing, and rappers became kings and queens.
