WWE Extreme Rules Collection

Extreme Rules is an annual pay-per-view (PPV) and WWE Network event produced by WWE since 2009. The concept of the show is that the event features various matches that are contested under hardcore rules, with at least one of them being an Extreme Rules match.[1] 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; WWE adopted the term and has since used it in place of "hardcore match" or "hardcore rules."
