Let's be real: Outside the United States, soccer reigns supreme over the sports kingdom.
This isn't to say that other major sports are ignored; the NFL has courted pro football fans in the U.K. through its series of games in London, and the NBA has found a passionate and largely untapped well of pro basketball fans in China and throughout Asia.
