WWE SummerSlam 2008 drew 467,000 buys on pay-per-view, 294,000 in North America, according to the Wrestling Observer Newsletter. The event was down 14% overall from 2007 and 15% in North America. The event marked the second straight double digit year over year decline for WWE pay-per-view events after a strong start to the year.
In the same pay per view environment, the UFC has seen 15 to 20% gains in year over year numbers for the same time period. That is an impressive performance when juxtaposed with the WWE’s precipitous declines.
