Ultimate Fighting Championship (UFC) is turning 20.

Considering what a shit-show it was back in 1993, that's quite an accomplishment. And what 20th anniversary would be complete without a two-hour documentary?

That's where FOX Sports 1 comes in.

The network will air Fighting for a Generation: 20 Years of UFC later tonight (Tues., Nov. 5, 2013) at 9 p.m. ET, which takes an in-depth look at the rise of the world's pre-eminent mixed martial arts (MMA) organization. featuring more than 60 interviews from past and present owners, fighters, celebrities and politicians.

Even Senator John "Human Cockfighting" McCain, according to the official release:

McCain discusses what he initially thought of the UFC, and how his opinion has changed: "I was appalled," he says of what he saw in the early days. "It was a matter of safety, the health and life of the combatants. I was interested in stopping the barbaric behavior that put people's lives at risk." Now he believes the UFC is legitimate. "It's become a sport with amazing popularity and success. There are rules, there are regulations, and there are restrictions and that I think has been a dramatic improvement and I'm very pleased to see it."

Here's a sneak peek:
