You mean in one place that offers very little (if any?) real sport competition? More people in Korea would be watching a successful South Korean soccer team then even the biggest of star craft 2 events. The market is small, the market is tiny. It only seems large because of the internet. In reality the market for spectator e-sports is very small (and beyond star craft it is pretty much non-existent). The only way e-sports will ever become a profitable market beyond niche is to engage it at the casual player with accessible leagues/ladders/ and tournaments for all. Blizzard kind of does it but they don't provide a good interface for it in my opinion. All others who try have failed pretty hard. Beyond sc2 e-sports have been declining and failing left right and center. And absolutely nothing that I see coming from game companies give me faith that this will change. Star craft 2 is a nice niche but it does not represent the e-sports market as a whole. That market is tiny, and largely ignored and at the current time requires real innovation. In my opinion the real money in e-sports (when it finally does get big) will not be spectating at all, it will come from little Johny paying 5$ a month to play in a very well run, exiting, competitive and fun casual league. Someone just needs to build it right.
