The Vertigo Tour was a worldwide concert tour by the Irish rock band U2. Launched in support of the group's 2004 album How to Dismantle an Atomic Bomb, the visited arenas and stadiums from 2005 through 2006. The Vertigo Tour consisted of five legs that alternated between indoor arena shows in North America and outdoor stadium shows internationally. Much like the previous Elevation Tour, the indoor portion of the Vertigo Tour featured a stripped-down, intimate stage design. Protruding from the main stage was an ellipse-shaped "B stage" that encapsulated a small number of fans.
The tour grossed $260 million in 110 sold-out concerts in 2005, making it the top-grossing tour of the year. In North America alone, the tour grossed $138.9 million with around 1.4 million tickets sold. The Vertigo Tour won the 2005 Billboard Roadwork Touring Awards for Top Tour, Top Draw, and Top Single Event. By the time it finished, the Vertigo Tour had sold 4,619,021 tickets — with 131 shows — for a total gross of $389 million; the gross was the second-highest such figure ever. The tour was depicted in the three concert films, Vertigo 2005: Live from Chicago, Vertigo: Live from Milan, and U2 3D.
