According to USA Today, millions of gift-wrapped iPads, Kindles, Nooks and other digital reading devices resulted in an unprecedented surge in sales of e-books last week.
E-book versions of the top six books outsold the print versions last week. And of the top 50, 19 had higher e-book than print sales.
It's the first time the top-50 list has had more than two titles in which the e-version outsold print.
"Lots of consumers woke up Christmas morning with new e-reading devices ready to load them up with e-books," says Paul Bogaards of Knopf.
