To understand the contributions of White and the Fertittas, one must understand that the orgins of UFC are clouded with government censorship. Intially, in UFC there were almost no rules; including no weight classes or divisions. Let me be clear, this is not prowrestling. UFC is comprised of actual fighters from different disciplines. Many people called for the UFC matches to be disbanded because of the violence. Over time, there became more rules, including weight classes. Some of the contraversy died down.
The Fertittas bought UFC with their company Zuffa and made White the President. When White and the Fertittas took over in 2001, they began to get state commision sanctioning, which gave the sport some legtimacy. Under their watch, UFC was showcased on cable pay-per-views and other cable outlets, like Fox Sports and Spike TV. White's vision for UFC is to take the fights to the masses:
If you take four street corners, and on one they are playing baseball, on another they are playing basketball and on the other, street hockey. On the fourth corner, a fight breaks out. Where does the crowd go? They all go to the fight.
Today we honor Dana White, Frank Fertitta, and Lorenzo Fertitta for their direction and innovations that made UFC a wealth creating entity.
