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
Development on the set design began in the middle of 2007. The building of the actual set began in the middle of March 2008. 100 people worked 16 hours a day to construct the set for the event. The construction finished on March 29. WrestleMania XXIV was the first WrestleMania event to be filmed in high-definition. It was also the first WWE show and sports related title to be released on the Blu-ray Disc format by WWE Home Video. WrestleMania also led to an increase in sales for musical artists related to the event, including the Red Hot Chili Peppers' album "Stadium Arcadium", John Legend's album "Live from Philadelphia", Rev Theory's single "Light It Up", and Fuel's single "Leave the Memories Alone", which was used as part of a tribute to Ric Flair.
