The Pacman just got 1.15 million buys for his fight with Antonio Margarito. That gives the Pacman three of the 16 bouts that exceeded one million buys in terms of PPV. Floyd Mayweather, Jr. has three million dollar sellers as well, which is probably why so many people think the Pacquiao-Mayweather has to be made at some point. The money is too great.
Here's a quick look at all 16 fights that make up the list. A couple of caveats: This is only North American PPV. So don't get upset that I'm not including worldwide totals. But all of these bouts sold well overseas as well.
