WrestleMania 23

WrestleMania 23 was a 2007 professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE). It was the 23rd annual WrestleMania and took place on April 1, 2007, at Ford Field in Detroit, Michigan, held for wrestlers from the promotion's Raw, SmackDown!, and ECW brand divisions. It was the second WrestleMania to take place in the Detroit metropolitan area, after WrestleMania III, which was held at the Pontiac Silverdome in Pontiac, Michigan. It was also the first WrestleMania to feature the ECW brand following its establishment as WWE's third brand in May 2006. This was the final WrestleMania to air in 4:3 standard definition.

Eight professional wrestling matches were scheduled for the event, which featured a supercard, a scheduling of more than one main event. The main event of the show, which was the main match on the Raw brand, was John Cena versus Shawn Michaels for the WWE Championship, in which Cena won. The predominant match on the SmackDown! brand was Dave Bautista versus The Undertaker for the World Heavyweight Championship, in which The Undertaker was victorious. The primary match on the ECW brand saw ECW World Champion Bobby Lashley (representing Donald Trump) defeat Raw's Intercontinental Champion Umaga (representing Vince McMahon) in a match where either Trump or McMahon would be shaved bald if their wrestler lost. The match was billed as the "Battle of the Billionaires". Other featured matches included an eight-man tag team match between The ECW Originals and The New Breed and an eight-man interpromotional Money in the Bank ladder match.

Tickets for the event went on sale on November 11, 2006. The event set the all-time Ford Field attendance record of 74,287 people; people from all fifty U.S. states, twenty-four countries, and nine Canadian provinces attended the event. WrestleMania 23 grossed $5.38 million in ticket sales, breaking the previous record of $3.9 million held by WrestleMania X8. WWE estimated that $25 million was pumped into the Detroit economy. With about 1.2 million buys, the event, at the time, was the most bought WWE pay-per-view in history at the time. WrestleMania XXVIII in 2012 surpassed the event as the most bought WWE pay-per-view, receiving 1.21 million buys. WrestleMania 23 was also the fifth highest attended WrestleMania in history behind only WrestleMania 29 (which drew 80,676 fans), WrestleMania 35 (which drew 82,265 fans), WrestleMania III (which drew 93,173 fans), and WrestleMania 32 (which drew 101,763 fans).
