American recording artist Britney Spears has embarked in five concert tours, four of which have been worldwide. Her first tour happened as an opening act for 'N Sync. Spears' 1999–2000 headlining debut, the ...Baby One More Time Tour, was based in North America only, and its success prompted an extension of dates entitled Crazy 2K. The tour was positively received by critics, but generated some controversy due to her racy outfits. Jae-Ha Kim of the Chicago Sun-Times commented that "Spears has that 'it' factor that worked for pinup queens of the past". In 2000–01, she performed on the worldwide Oops!... I Did It Again World Tour. It was critically appreciated for Spears' energy and performance, as well as the band. She then followed this with the Dream Within a Dream Tour in 2001–02, visiting Japan and Mexico for the first time. The performances were accompanied by many special effects, the pièce de résistance being a water screen that pumped two tons of water into the stage during the encore performance of "...Baby One More Time". Other moments included singing "Oops!... I Did It Again" in a girating wheel and jumping in bungee cords for "I Love Rock 'n' Roll".

The Dream Within a Dream Tour was followed by 2004's The Onyx Hotel Tour. Spears was inspired to create a show set in different areas of a hotel, and mixed it with the concept of an onyx stone, that symbolized untapped desire. The tour was cancelled after Spears hurt her knee while shooting the music video for "Outrageous". The Onyx Hotel Tour grossed $34 million, in addition to $30 million of merchandise, making Spears the highest grossing female artist. She did not tour again until The Circus Starring Britney Spears. All the North American shows were sold out, and it broke attendance records in some cities. It went on to become the fifth highest grossing tour of 2009, as well as the fifth highest grossing tour ever by a female artist, with approximately US $131.8 million in ticket sales. As of September 2009, Spears has performed concerts for over ten million people. Spears has also embarked in two promotional tours: the L'Oreal Hair Zone Tour (1998) and The M+M's Tour (2007).
