The game was played at the Louisiana Superdome in New Orleans, Louisiana, on February 3, 2002. Following the September 11, 2001 terrorist attacks earlier in the season, the NFL postponed a week of regular-season games and moved the league's playoff schedule back. As a result, Super Bowl XXXVI was rescheduled from the original date of January 27 to February 3, becoming the first Super Bowl played in February. The pregame ceremonies and the halftime show headlined by the Irish rock band U2 honored the victims of 9/11. Due to heightened security measures following the attacks, this was the first Super Bowl designated as a National Special Security Event (NSSE) by the Office of Homeland Security (OHS). The Department of Homeland Security (DHS), which replaced the OHS in 2003, later established the practice of naming each subsequent Super Bowl an NSSE. Additionally, it was the last Super Bowl to be played in New Orleans before Hurricane Katrina slammed the city on August 29, 2005; the first since then was Super Bowl XLVII in 2013.
