One of the Fertitta brothers who are the main owners of the UFC quit his post at Station Casinos to work with the UFC full time. Last year he made over 100 million in his position at the casino, while he'll still get a good cut of Station's money since it's a family owned business, that shows you what potential money there may be in MMA.
Looking to expand more internationally and get more major sponsors, pure speculation from me, but I bet he works hard on a network tv deal as well
