Even in this pretty down year with I think it's now 13 PPV's with the axe falling on this one they are still averaging around 400-500K PPV buys per event.
That's a really loose use of that number Dave. These are the buyrates to date for this year:
UFC 142: 225K Main Event Weight Class: Featherweight
UFC 143: 400K Main Event Weight Class: Welterweight
UFC 144: 375K Main Event Weight Class: Lightweight
UFC 145: 700K Main Event Weight Class: Light Heavyweight
UFC 146: 500K Main Event Weight Class: Heavyweight
UFC 147: 140K Main Event Weight Class: Light Heavyweight
UFC 148: 1M Main Event Weight Class: Middleweight
UFC 149: 235K Main Event Weight Class: Bantamweight
UFC 150: 190K Main Event Weight Class: Lightweight
Which averages out to 418,000-ish per event on the strength of 148...but look at the low numbers recently. PPV and TV numbers seem to suggest UFC 151 would probably do in the neighborhood of UFC 145, and UFC 152 would unfortunately do in the neighborhood of UFC 142. I don't know what it is that draws people to heavyweight fights and not the smaller weight classes (Anderson Silva and GSP aside,) but I don't think UFC 152 was going to do more than 250,000 buys, if that.
Interesting times, that's for sure.
