UFC remains king of PPV hill - UFC - Yahoo! Sports

After setting pay-per-view industry records in 2009, the Ultimate Fighting Championship faces opposition from boxing and wrestling over the next several months as it attempts to maintain last year’s levels.
It’s estimated that UFC, which didn’t publicly release figures, did nearly 8 million buys in the United States and Canada on 13 pay-per-view events this past year. That includes six of the year’s top 10 buyrates and 11 of the top 15.
