Summerslam is a PPV in Smackdown Vs Raw 2006, Smackdown Vs Raw 2007, and Smackdown Vs Raw 2008. It is a part of the big four, and features all brands. It takes place in the month of August, and is usually the first big four PPV on the schedule. Despite being a big four PPV, it features no interbrand matches, and instead divides the match card between the brands.
Summerslam features six matches (later five in Smackdown Vs Raw 2008), split evenly between Raw and Smackdown. The brand receiving the best ratings will receive more fans than the other. Later, when ECW is added in Smackdown Vs Raw 2008, the five matches are split based on who has the most viewers when the show starts. The show with the most viewers will have the main event and third match. The show with the second most ratings will receive the second and fourth match. The show with the lowest viewers will receive the first match.
