It goes without saying that the Ultimate Fighting Championship remains far and away the biggest, most powerful mixed martial arts organization on the planet. Worth more than a billion dollars and wielding enough resources to host an average of one event per week on multiple platforms, the UFC might rule the MMA universe until a comet destroys Earth.

As dominant a force as the UFC has become, it was not always this way. In fact, there were a number of times when the so-called “Super Bowl of Mixed Martial Arts” was on the verge of collapse. However, a series of fortunate events led the UFC to a place of power in combat sports.

The latest installment in the Sherdog Top 10 series examines the greatest moments in UFC history, the moments that helped bring the Las Vegas-based promotion to where it is today.
