The 2010 event became the first event of what is now one of WWE's yearly pay-per-views. An Elimination Chamber event has occurred every year since except in 2016. It has also mostly occurred in February, except for the 2015 event, which was held in May, and the 2020 event held in March. While originally designed for single competitors, the first tag team Elimination Chamber match occurred at the 2015 event. The chamber itself was redesigned for the 2017 event, becoming square in design. A women's version of the match first occurred at the 2018 event, which also featured the first seven-man chamber match.
