The show's name also referred to the ECW brand, in which WWE employees were assigned to work and perform, complementary to WWE's other brands, Raw and SmackDown. It debuted on June 13, 2006 on Sci Fi in the United States and ran for close to four years until it aired its final episode on February 16, 2010 on the rebranded Syfy.
