Since opening, the United Center has hosted over 200 events each year. Some of the events the United Center has been proud to host include The Rolling Stones, Eric Clapton, Bruce Springsteen, Paul McCartney, U2, The 3 Tenors, Disney on Ice, the Great Eight Classic, Illinois College Basketball and so much more. The United Center has hosted over twenty million guests since its opening in 1994.
