Hell in a Cell is a professional wrestling event produced annually by WWE, a Connecticut–based professional wrestling promotion, and broadcast live and available only through pay-per-view (PPV) and the WWE Network. The event was established in 2009, replacing No Mercy in the early October slot of WWE's pay-per-view calendar. In 2012, WWE announced that Hell in a Cell will be moving to late October, leaving only one pay-per-view in October. However, in 2013 WWE added Battleground (originally as Over the Limit) in an early October slot.
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. Hell in a Cell was chosen over No Escape, Locked Up and Rage in a Cage.
Since its origin, the event has been held only in indoor arenas in the United States. Championship bouts are scheduled on every card, with the lower-tier titles contested on the undercard and the top-tier appearing on the main card.
