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 XXVII
WrestleMania XXVII was a joint-promotion event, with performers from both the Raw and SmackDown brands. This would be the last joint-promotion WrestleMania until WrestleMania 33 in 2017; the first brand split ended in August 2011, meaning that performers were no longer exclusive to a brand, but the brand split returned in mid-2016. The event's card consisted of eight matches, including three main matches. In the first, Edge defeated Alberto Del Rio to retain the World Heavyweight Championship in what turned out to be Edge's final televised match before his retirement one week later due to cervical spinal stenosis in his neck. The second saw The Undertaker defeating Triple H in a No Holds Barred match to extend his undefeated WrestleMania streak to 19-0. The third saw The Miz defeating John Cena to retain the WWE Championship. This is the only WrestleMania where no championships changed hands; three championships were defended at the event and all three were retained.
