PopOdyssey was the fourth concert tour by American boy band NSYNC. Sponsored by Verizon Wireless and Chili's, the tour promoted the band's third studio album, Celebrity. The tour's name is defined as "an adventurous journey towards popularity, beginning as just a dream and ending in reality". The tour became the biggest production in pop music, beating U2's PopMart Tour. The tour, which visited stadiums, was NSYNC's first to include backup dancers, and is known for its elaborate audio and visual effects which included lasers, fireworks, animation, and suspension wires.
