In early-to-mid-2002, then World Wrestling Federation (WWF) underwent a process they called the "brand extension".[2] The WWF divided itself into two de facto wrestling promotions with separate rosters, storylines and authority figures.[2] Raw and SmackDown! would host each division, give its name to the division and essentially compete against each other. The split came about as a result of the WWF purchasing their two biggest competitors, World Championship Wrestling (WCW) and Extreme Championship Wrestling (ECW); and the subsequent doubling of its roster and championships. The brand extension was publicly announced by Linda McMahon during a telecast of Raw on March 25 and became official the next day.
