WrestleMania XXVI
Along with WrestleMania XXVI, a series of events grouped as "WrestleMania Week" were held in the week preceding the event. To begin promotion for the event in Glendale, a "Kick-off Party" was held at the Westgate City Center on March 19, which included appearances from WWE wrestlers, autograph signings and live entertainment along with a giant LED screen viewing of that night's episode of "SmackDown". The third annual "WrestleMania Art" (formerly "WrestleManiArt"), an art exhibition and auction featuring work by WWE superstars, was held on March 24 at the Make-A-Wish Foundation National Headquarters. WrestleMania's annual fan convention, WrestleMania Axxess, was held from March 25 through March 28 at the Phoenix Convention Center. On March 27, WWE hosted its annual WWE Hall of Fame ceremony at the Dodge Theater, where the Class of 2010 were inducted.
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.
