Amazon says it sells more books for Kindle than paperbacks and hardbacks combined on Amazon.co.uk, TechWeek Europe reports.

Amazon said that for every 100 print books bought through its UK site, it sold 112 Kindle books. Free Kindle books were excluded from the calculations and if included would have made the gap even wider, Amazon said.

“We hit this milestone in the U.S. less than four years after introducing Kindle, so to reach this landmark after just two years in the UK is remarkable and shows how quickly UK readers are embracing Kindle,” said Jorrit Van der Meulen, vice president for Kindle EU.
