U2 kicked off their ongoing 360° worldwide concert Tour in support of their album ‘No Line on the Horizon’ in June 2009. The Tour has been named after the 360-degree staging system and audience configuration, the band uses for all its shows.

U2 360° became the highest-grossing concert Tour ever in April 2011, when it grossed more than $700 million in ticket sales. The Tour has won U2 the Billboard Touring Award for the highest-grossing tour in 2009.

The tour will end on July 30, 2011.
