Amazon has announced that Kindle ebook sales now outnumber physical paperback and hardback sales, the digital platform overtaking print in just four years. Since April 1, Amazon says, it has sold 105 Kindle ebooks for every 100 print books on its US site. That’s not just limited to cases where both formats are available, either; it takes into account print titles where no Kindle equivalent is on offer (though free Kindle ebooks aren’t counted).
