Hell in a Cell
WWE Hell in a Cell is a professional wrestling event produced annually by WWE, a Connecticut-based professional wrestling promotion. It is broadcast live and available only through pay-per-view (PPV) and the WWE Network. First held in 2009, the concept of the show comes from WWE's established Hell in a Cell match, in which competitors fight inside a 20-foot-high roofed cell structure surrounding the ring and ringside area. Each main event match of the card is contested under the Hell in a Cell stipulation, while one or two other Hell in a Cell matches may occur on the undercard.
