WWE TLC: Tables, Ladders & Chairs was a professional wrestling event produced by WWE, a Connecticut-based promotion. It was broadcast live and available only through pay-per-view (PPV) and the WWE Network. The event was established in 2009, replacing Armageddon in the December slot of WWE's pay-per-view calendar. In 2017, the event was moved to October, but returned to December in 2018. An event was scheduled for 2021, but it was canceled in favor of a New Year's Day event called Day 1. The concept of the TLC event was based on the primary matches of the card each containing a stipulation using tables, ladders, and/or chairs as legal weapons, with the main event generally contested as a Tables, Ladders, and Chairs match.
