On November 14th, Ronda Rousey, professional UFC fighter and champion of her division was defeated by challenger Holly Holm.  This unexpected event raked in a massive crowd of just under 60,000 people, as well as people watching online electronically.  The event was trending at over 1 million pay per view buys, as well as the live gate accumulating around 6.7 million dollars.  The combined revenue of both the pay per view buys, as well as buy in at the gate was an number estimated at around 50 million dollars.  This amount of revenue from just one event however, shrivels in comparison to many other boxing and UFC events, such as the Manny Pacquiao-Floyd Mayweather fight, which brought in 400 million from just TV revenue alone.
