WrestleMania XXIV was the 24th annual WrestleMania professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE). It was held for wrestlers from the promotion's Raw, SmackDown, and ECW brand divisions. The event took place on March 30, 2008, at the Florida Citrus Bowl in Orlando, Florida and was the first WrestleMania to be held in the state of Florida. It was also the second WrestleMania to be held outdoors, with the first being WrestleMania IX.
Nine professional wrestling matches were scheduled for the event, which featured a supercard, a scheduling of more than one main event. In the final match of the event, which was the main match from SmackDown, The Undertaker defeated Edge to win the World Heavyweight Championship. Raw's main match was a triple threat match, in which Randy Orton defeated Triple H and John Cena to retain the WWE Championship. The main match from the ECW brand was a singles match in which Kane defeated Chavo Guerrero to win the ECW Championship. From the six scheduled bouts on the undercard, three received more promotion than the others. In a No Disqualification match, professional boxer Floyd "Money" Mayweather defeated Big Show. The other featured undercard matches saw CM Punk win the inter-promotional Money in the Bank ladder match and a retirement match in which Shawn Michaels defeated Ric Flair, leading to Flair's departure from the WWE and a period of retirement from active wrestling.
Tickets for the event commenced sale to the public on November 3, 2007. WWE and the City of Orlando hosted festivities that spanned a five-day period within the central Florida region. For the second consecutive year, WrestleMania broke the record for the highest-grossing pay-per-view in WWE history. It also set a gate record for the Citrus Bowl, grossing US$5.85 million in ticket sales. According to a study by Enigma Research Corporation of Toronto, the Citrus Bowl's record-breaking attendance brought an estimated $51.5 million – surpassing the projected $25 million – into the local economy and generated $1.8 million in local tax revenue. The Central Florida Sports Commission reported that the event created jobs and brought approximately 60,000 visitors to the city. Over one million people ordered the event on pay-per-view, grossing $23.8 million in revenue. It was also the first WrestleMania PPV broadcast in high definition.
