Ticket sales for major concert tours across North America have fallen to their lowest point since 2005, a US trade publication has said. During the first half of the year, the top 100 tours made a total of $965.5m (£636.2m), the lowest since 2005 when gross revenue was $730.9m (£481.6m). It marks a 17% decrease from the same period last year. Pollstar magazine said an average of 6,951 tickets per show were sold, down 9% from the same period in 2009. The Jonas Brothers, The Eagles, Christina Aguilera, Rihanna, John Mayer and Limp Bizkit have pulled summer dates in the US |
