The brand extension, also referred to as the brand split, is the separation of the American professional wrestling promotion WWE's roster of wrestlers (and, at various times, creative staff) into distinct divisions, or "brands". The promotion's wrestlers are assigned to a brand via the annual WWE Draft and exclusively perform on that brand's weekly television show, with some exceptions. Throughout its history, WWE has utilized the brand extension twice. The first brand split occurred from 2002 to 2011, while the ongoing second began in 2016.
WWE currently promotes four brands. The two main brands, referred to as the main roster, are Raw and SmackDown. NXT, WWE's third brand, was launched in 2010 and has served as WWE's developmental territory since 2012. A fourth brand, Evolve, launched in March 2025 as a sister brand to NXT and features trainees from the WWE Performance Center and independent wrestlers recruited for the WWE Independent Development program.
