X Factor U.K. contestants One Direction can lay claim to the fastest-selling album of all-time based on pre-orders for Midnight Memories, while Adele is the site's best-selling artist, with Lady Gaga and Rihanna also in the top five.

Coldplay and The Beatles came in ahead of both the U.S. female stars.

Call of Duty: Modern Warfare 2 tops the games chart, but Grand Theft Auto V drives off as the fastest-selling gaming title ever.

Amazon's digital VOD and DVD rental arm, Lovefilm, also noted that Despicable Me is the most-streamed film on the service.

"The past 15 years have seen Amazon.co.uk broaden its range of products each year, but entertainment products have always played an integral role in our business," said Xavier Garambois, vp of EU retail at Amazon. "It's fascinating to look back at our biggest sellers -- it gives a wonderful picture of the icons of entertainment culture [that] have defined the U.K. since 1998."

Focus Features will be pleased with the best-selling book data over the past 15 years.

The three EL James' Fifty Shades installments occupy the top three positions in the best-selling books by title. Despite its speedy record-breaking sales record, Harry Potter and the Deathly Hallows came in at No. 10 on the best-sellers' chart.
