Fun fact about US sports and the discrapency between the actual and perceived size of the sports ecomony. I'll include the entire quote from the expert from a freakonomics podcast:
DUBNER: What can you tell us about the size of the sports industry, and how it compares to other industries?
MATHESON: So the answer here is actually surprisingly small. So the biggest league in the world in terms of revenue generated is the N.F.L. And the N.F.L. generates something like $14, $15 billion a year. Now you might be thinking to yourself, well, 14, 15 that sounds like a lot of money. That’s roughly the same size as Sherwin-Williams. So the typical American buys as much paint from Sherwin-Williams as it does by buying N.F.L. products from the largest league in the world. You add in all these other American leagues — N.B.A., Major League Baseball, the N.H.L., Major League Soccer, plus the P.G.A. and pro tennis, and mixed martial arts and all these things — add them all up together, you’ve got maybe $50 billion of pro sports, a few more tens of billions of dollars in college sports. But you’re still only up at 60, 70 billion dollars. That makes spectator sports in the United States roughly the same size as the cardboard-box industry in the United States. Now obviously none of us gather around the water cooler on Monday morning saying, “Hey man, did you see that awesome cardboard box that American Paper just put out?” Of course we don’t. So sports has a social impact that is way way bigger than its economic impact.
