WWE Extreme Rules is a professional wrestling event produced annually by WWE, a Connecticut-based promotion. It is broadcast live and available only through pay-per-view (PPV) and the livestreaming services Peacock and the WWE Network. The name of the event stems from various matches on the card being contested under hardcore wrestling regulations with generally one match being an Extreme Rules match, introduced at the 2010 event. The defunct Extreme Championship Wrestling promotion, which WWE acquired in 2003, originally used the "extreme rules" term to describe the regulations for all of its matches. The event name was established in 2009; however, its theme began with its predecessor, One Night Stand, which was promoted in 2005 and 2006 as an Extreme Championship Wrestling reunion show. In 2007, WWE promoted the show as one of its own regular pay-per-view events but kept the concept of hardcore-based matches. In 2009, WWE renamed the One Night Stand event to Extreme Rules. The 2009 Extreme Rules event was noted by WWE to be a direct continuation of the One Night Stand chronology. However, the 2010 event was later promoted as only the second event under a new chronology, one that is no longer a direct continuation of the One Night Stand events. 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 replaced Over the Limit as that year's May PPV. 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 and was held 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 only, the event was titled The Horror Show at Extreme Rules. The 2021 event was then moved to September, replacing Clash of Champions. The 2022 event was moved to October and was the first time for the event to be held on a Saturday. Concept and History From 2005 to 2008, World Wrestling Entertainment (WWE) ran a pay-per-view (PPV) entitled One Night Stand. While originally a reunion show for the defunct Extreme Championship Wrestling promotion, the assets of which WWE acquired in 2003, the concept of One Night Stand was that the event featured various matches that were contested under hardcore rules.
