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 XXV
As the second WrestleMania to be held in Houston and the state of Texas after WrestleMania X-Seven at the Astrodome, WWE mainly promoted WrestleMania XXV under the tagline ""Everything Is Bigger in Texas, Especially WrestleMania"" since its announcement at WrestleMania XXIV in March 2008. WWE later began using ""The 25th Anniversary of WrestleMania"" name in late-2008 to primarily promote the event. Tickets for WrestleMania XXV were originally scheduled to go on sale September 20, 2008, but had to be postponed out of concern for the residents near the Gulf of Mexico due to Hurricane Ike and the disaster area declaration by Texas Governor Rick Perry. Following another postponement due to the effect of Ike on the state of Texas, WWE announced that ticket sales would be postponed until November 8, 2008.
