Starting in 2010, Extreme Rules was moved from June to late April/early May to replace Backlash as the post-WrestleMania pay-per-view event. For 2013, the event was scheduled to take place in mid-May and replaced Over the Limit. After the reinstated brand extension took effect in mid-2016, the event returned to the June slot of WWE's pay-per-view calendar in 2017 as a Raw-exclusive pay-per-view event. Following WrestleMania 34 in 2018, however, all WWE pay-per-views ceased being brand exclusive, and Extreme Rules moved to the July slot. For the 2020 edition, the event was titled The Horror Show at Extreme Rules. The 2021 event was then moved to September.
