With Dave Meltzer reporting a preliminary buyrate of between 750-810,000 for UFC 141 according to MMA Manifesto I can report that UFC over the course of sixteen PPV events drew 6,715,000-6,785,000 buys in 2011. The highest grossing events being 129 and 141 both drawing 800,000 buys or more and both headlined by Brock Lesnar and GSP who both remain the companies biggest draws.
The UFC drew roughly 2.6 million less buys than 2010 when the UFC drew 9,305,000 buys. The reason's for this include significant Injuries (nearly every event lost a main or co-main event to injury), poor scheduling (136 being two weeks after 135), the end of there current TV deals and PPV fatigue.
The Top Five PPV's for the UFC in 2011 were (Dave Meltzer provides the numbers):
UFC 141: Lesnar vs. Overeem- 750-810,000 buys
UFC 129: St. Pierre vs. Shields- 800,000 buys
UFC 126: Silva vs. Belfort- 725,000 buys
UFC 135: Jones vs. Rampage- 520,000 buys
UFC 128: Shogun vs. Jones-490,000 buys
The Bottom five were:
UFC 139: Shogun vs. Henderson- 290,000 buys
UFC 137: Penn vs. Diaz- 280,000 buys
UFC 125: Resolution- 270,000 buys
UFC 127: Penn vs. Fitch- 260,000 buys
UFC 136: Edgar vs. Maynard 3- 225,000 buys
With the retirement of Brock Lesnar and GSP's injury the UFC will need to create new star's in order to reverse this dramatic decline in 2012. With Jose Aldo and Chad Mendes headlining the UFC's first event of 2012 I don't expect a great start.
