SummerSlam is the WWE's second-biggest show of the year, but there have been times throughout the near 30-year history of the event where it stole the spotlight from WrestleMania by being the better show.

For the first time ever, the leader in sports entertainment is having its annual summer spectacular go on for two nights. Thanks to the massive success that WrestleMania has experienced with holding two nights of action, the promotion has decided to take its second biggest premium live event, and give it two nights of exhilarating action.
