History: More commonly known as The O2 Arena after its sponsor but renamed for the Games because of the International Olympic Committee's strict sponsorship regulations, the venue began its existence as the Millennium Experience in 2000. It was then redeveloped and transformed into an entertainment complex, opening in 2007 as the second largest indoor arena in the UK. Within a year it had earned a reputation as the world's busiest music venue by selling more than two million tickets to concerts by UK and global stars. Last year it hosted the Brit Awards for the first time. But it is not just a music complex. The arena has also staged the ATP Tour Finals season-ending tennis tournament since 2009, as well as NHL ice hockey and NBA basketball games, the World Artistic Gymnastics Championships, mixed martial arts, professional boxing and wrestling, darts, ice dancing and stand-up comedy.
