As in other professional wrestling promotions, WWE shows are not legitimate contests, but purely entertainment-based, featuring storyline-driven, scripted, and choreographed matches, though they often include moves that can put performers at risk of injury if not performed correctly. This was first publicly acknowledged by WWE's owner Vince McMahon in 1989 to avoid taxes from athletic commissions. Since the 1980s, WWE publicly branded their product as sports entertainment, which is considered to acknowledge the product's roots in competitive sport and dramatic theater.
