 WCW continued to lose more money and finally folded on March 23, 2001, with McMahon buying out the promotion, after more than 15 years of business.In 2002, the WWF was renamed "World Wrestling Entertainment" to avoid a trademark dispute with the World Wildlife Fund.Not long after the closure of WCW and ECW, new promotions were founded in an attempt to cater to a niche market for the Southern-style, Lucha Libre, strong style, and hardcore wrestling styles that had been displaced by WWE.
