The event's name was selected after WWE allowed fans to provide input via a survey on their official website and was chosen over Heavy Metal, Battle Chamber, Chamber of Conflict, and the original No Way Out name. Since its origin, each event has been held in an indoor arena, with all nine taking place in the United States. In 2015, the event was replaced by Fastlane in the February pay-per-view slot. However, the 2015 event was later announced to be streamed exclusively on the WWE Network in the United States on May 31 and was also available on PPV elsewhere. The event did not occur in 2016, but returned in 2017 as a SmackDown-branded event for the first time, following the introduction of the second brand split. The 2018 event was a Raw-branded show. While the eponymous match was originally only for male wrestlers, the 2018 event featured the first-ever women's version, as well as the first seven-man Elimination Chamber match. Following that year's WrestleMania 34, WWE discontinued brand-exclusive pay-per-views, thus the 2019 event featured wrestlers from both the Raw and SmackDown brands, as well as 205 Live. The 2019 event also determined the inaugural holders of the WWE Women's Tag Team Championship. The 2020 event was moved to March as Super ShowDown was held in February, but Elimination Chamber returned to its February slot in 2021.
