Extreme Championship Wrestling (ECW) was a promotion that was founded in Philadelphia, Pennsylvania in 1992 by Tod Gordon. ECW closed when then owner Paul Heyman declared bankruptcy in April 2001. The promotion showcased various international styles of professional wrestling, ranging from lucha libre to puroresu and hardcore wrestling and became the #3 promotion in the US, on several occasions being used as a feeder fed by both WCW and WWE. After its closure most ECW talents were signed by WWE and became apart of the WCW-ECW Alliance Invasion storyline until they were absorbed into the main roster.
After purchasing the assets of ECW, World Wrestling Entertainment relaunched the Extreme Championship Wrestling franchise as a WWE brand with their existing Raw and SmackDown brands. 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. It was replaced the following week with WWE NXT.
