he went to tna
NWA World title
i think sting won
Sting was with the NWA (National Wrestling Alliance) and WCW (World Championship Wrestling) before he joined TNA
Sting defeated "The Nature Boy" Ric Flair for the NWA World Heavyweight Championship at the 1990 Great American Bash.
Sting never left the WWE, because he was never there to begin with. He's prominently known for his time in the NWA in the '80s, WCW in the '90s, and TNA in the 2000's, but he was never employed by the WWE.
Sting has never wrestled at Wrestlemania or at any other WWF/E event. Sting has never worked for McMahon Promotions in any way shape or form. The only footage the WWF/E have of him is NWA and WCW stuff. He is the only big name wrestler of the 1990's never to work for Vince McMahon.
NWA is straight out of Compton, California.
NWA Bloodfest happened in 1993.
NWA Rollergirls was created in 2006.
NWA Shockwave was created in 2001.
NWA Shockwave ended in 2007.
NWA Wildside ended in 2005.
