Elimination Chamber is a gimmick pay-per-view first produced by WWE in 2010. It had been held every year in February; 2015 was the first of two times in which the event occurred outside of that month and was held in May (the second was the 2020 event held in March that year). The concept of the show is that one or two main event matches are contested inside the Elimination Chamber, either with championships or future opportunities at championships at stake. 2015 was the sixth event under the Elimination Chamber chronology and featured the first-ever tag team Elimination Chamber match. It was also the last Elimination Chamber to be held until the 2017 event, subsequently also being the last before the reintroduction of the brand extension in July 2016, which again split the roster between the Raw and SmackDown brands.
