By April 2002, with an excess of talent employed as a result of having purchased WCW and ECW, WWE needed a way to provide exposure for all of its talent. This problem was solved by introducing a "Brand Extension", with the roster split in half and the talent assigned to either Raw or SmackDown! in a mock draft lottery. Wrestlers, commentators and referees became show-exclusive, and the shows were given separate on-screen General Managers. The brand extension came into effect on April 1, 2002.
