Certainly not dollars. But it's definitely high in participation and in popularity in other countries. All these smaller countries (especially in Africa) that can't afford the proper equipment or training for other sports end up running since it doesn't require money to get you started. Granted, in many of those cases it may be due to a lack of options, but it's still huge. Just look at the Olympics. You go to watch most of the basketball games and there were empty seats in the arenas that hold what, 25,000 people? But the track stadium with a capacity of 91,000 was basically filled to the brim. It may not be second (I forgot where I found that article, so I can't site it right now), but it's definitely up there. Look at the other options. Baseball isn't even an Olympic sport anymore. Basketball is big here and in Europe, but it gets most of it's attention here. Football is really only our thing. Cricket could probably beat it out. Up until a few years ago Cricket questions were on the forms to become a citizen of Australia. Hockey, mostly Canada.
