We don't know what the actual numbers are, but a somewhat intelligent person can realize that people are watching. People are buying their product.
The proof is in the frequency and growth around the world. How could they be putting on shows around the world and not have people watching?

Dave Meltzer of the Wrestling Observer is reporting that buyrates for the latest UFC PPV in Sydney, Australia are trending very low.
Updated trending data and other PPV info we’ve been able to get for UFC 110 isn’t looking good. It looks to have finished well behind UFC 108 and UFC 109. I don’t have a number of buys, but based on trending data which has historically been pretty accurate, it could be in the 215,000 to 240,000 range, basically along the lines of the tape-delayed foreign shows. This was foreign, but wasn’t tape delayed. One cable industry source gave an estimate of 215,000.
Payout Perspective:
We’ve talked a lot about the role that momentum plays in motivating purchasing behavior, and three lacklustre PPVs in a row have clearly hurt the UFC’s base. Should anyone be worried? Yes and no.
This is really the last lingering effect from the cursed back-half of 2009 when just about every major UFC star had some sort of injury; and, with a line-up in the next three months that’s going to feature four title fights, the UFC should be able to gather some momentum heading into the summer.
However, who’s to say what sort of impact this latest trend of poor PPV showings will have on UFC 111. The UFC isn’t necessarily out of the woods yet, especially considering the potential impact a strong or poor showing at UFC 111 could have for the rest of the summer. That’s why creating a Primetime show and spending a more than usual on advertising for this event is so important.
Note: Meltzer doesn’t have hard numbers, yet. These are just trending estimates that usually increase by10-15% over time. We’ve been loathe to post them in the past just because they do change. Readers are starving for this information and this is the best we’ve got right now, but we will update if/when official numbers come along.
