Organisers estimate that some 8 million tickets would be available for the Olympic Games, and 1.5 million tickets for the Paralympic Games. Ticket sign-up, in Great Britain, was launched on 22 March 2010 and the application website was opened on 15 March 2011 until 26 April 2011. Ticket prices range from £20 for many events to £2,012 for the most expensive seats at the opening ceremony. Ticket allocations for oversubscribed events was decided by a random ballot. For the first time in Olympic history the sailing events will be ticketed.
There was a huge demand for tickets as 20 million tickets were bought by 1.8 million people, three times the 6.6 million tickets available in the first round lot, with 95% of the applications from Great Britain.
