He is the Chairman of the World Wrestling Entertainment (WWE) Board of directors and majority shareholder of WWE. After acquiring World Championship Wrestling (WCW) in 2001 and Extreme Championship Wrestling (ECW) in 2003, two years after its closure, McMahon's WWE became the sole remaining major American professional wrestling promotion (prior to the national expansion of Total Nonstop Action Wrestling).
One of the worlds few "billionaire's" he runs his business with an iron fist. I know for a fact that the guys who work for him, have the absolute highest respect for him. They all say, the last thing they want to do is make Vince mad!
This picture was taken at a WWE event. I don't even remember where it was. I love the picture because the photographers camera froze up, Vince got mad and walked off. The Big Show was there (a client of mine as well) and pushed Vince back into the picture just in time for the picture! You can see him in the background laughing!
