SummerSlam is a WWE show.
 In July 2021, WWE resumed live touring with fans, and in an effort to sell out that year's SummerSlam, which was held at the Allegiant Stadium in the Las Vegas suburb of Paradise, Nevada, WWE promoted SummerSlam as the "biggest event of 2021"
 After the promotion resumed live touring with fans in July 2021, that year's SummerSlam was promoted as the "biggest event of 2021" due to WrestleMania 37 having to be held at a reduced venue capacity
