Summerslam's rich tradition as one of WWE's premiere annual shows continues in just weeks, as the company promotes its 27th annual blockbuster event. Not all WWE plans have come to fruition, others did and would result in classic matches with unbelievable back stories or financial implications. From unbeaten superstars, to insane payoffs, to matches that could have been, Summerslam has put a unique thumbprint on wrestling history both inside and outside of the ring. After taking the event throughout three countries, the show has developed into a regular west-coast attraction, as the WWE has made the Staples Center in Los Angeles the permanent fixture for the show since 2009. Even after 26 years, Summerslam remains one of the biggest pay-per-view shows of the year, and has been a launching pad and career highlight for the likes of Brock Lesnar, Davey Boy Smith, and many others. The show also served as a stage early on for the WWE to promote outside products, such as their infamous "No Holds Barred" film, which saw star Tiny Lister competing in a WWE ring during the 1989 event. We've compiled a comprehensive list of unbelievable stats about the event, which WWE calls "the biggest party of the summer." Some of these obscure fact will help you understand why.
