WrestleMania XXVI
Global Spectrum, the University of Phoenix Stadium's operator, had worked in previous years with World Wrestling Entertainment (WWE) to recruit the event to its venue. On January 18, 2008, Global Spectrum publicly announced its intention to host WrestleMania in 2010. The event gained media attention in the weeks prior when a photo of Wayne Gretzky, then head coach of the Phoenix Coyotes, wearing a shirt promoting the event surfaced in the Swedish newspaper "Expressen". A press conference, held on February 24, 2009 at the University of Phoenix Stadium, formally announced the event for Glendale, Arizona at the University of Phoenix Stadium; this event marked the first time a WrestleMania had taken place in the state of Arizona. Tickets for the event went on sale November 7, 2009 at 10:00am MST.
WrestleMania XXIV
Nine professional wrestling matches were scheduled for the event, which featured a supercard, a scheduling of more than one main event. The first of these matches was a singles match from the ECW brand, in which Kane defeated ECW Champion Chavo Guerrero to win the ECW title. The second was a Triple threat match from the Raw brand, in which WWE Champion Randy Orton defeated challengers Triple H and John Cena to retain the championship. In the final match of the event, The Undertaker defeated SmackDown's World Heavyweight Champion Edge to win the title. From the six scheduled bouts on the undercard, three received more promotion than the others. In a No Disqualification match, boxing champion Floyd "Money" Mayweather defeated Big Show. The other featured undercard matches saw CM Punk win an interpromotional 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.
