Thought while watching the Tempest on Netflix:

If there is the NFL

and NBA

and NASCAR

and Target

and Quiznos,

why isn't there a national for-profit league of theaters who produce their own pieces and have a season of going to each others houses putting up double bills or weekend two-fer one specials ending in a season playoff where audience members choose their favorite pieces? Once chosen, there could be a week long post-season festival of best-ofs and experimentals concluding with an all-star gala production featuring the most able people in the various capacities chosen from all of the league's member houses.

Or has that been done already?
