I think obviously the biggest 3 are usa, brazil, and canada. I think:
1. USA
2. Brazil
3. Canada
4. Russia
5. Japan
6. England
7. South Korea
8. Australia
9. Poland
10. China
11. Ireland
121,121. India
1. USA - obviously the biggest market.
2. Brazil - definitely the biggest market outside of the US.
3. Canada - definitely has a presence but it's overstated.
4. Russia - definitely a big & growing market for MMA.
5. Japan - MMA & pro-wrestling have been dying for a long time & most people have probably never heard of the UFC - could be a resurgence in future, at the moment though it's pretty dead there.
6. England - MMA still has a relatively small presence here. People are aware of MMA, but marketwise, at the moment it's not a big one compared to Boxing, not sure if it will ever be in the public eye or mainstream the way boxing is here.
7. South Korea - definitely an emerging/growing market for MMA, could potentially be a huge market for MMA.
8. Australia - pretty similar to the UK, MMA is not mainstream or particularly big.
9. Poland - big market for MMA, think this should be after Russia.
10. China - a big market but MMA is relatively non-existent here.
11. Ireland - not to sure about.
12. India - same as China, MMA is relatively non-existent here.
