I've jut come across an infographic that claims that the US isn't the country with the highest adoption rate for ebooks. If the data in this infographic is correct then Russia, with 70% of readers having tried ebooks, takes the crown.
That's much higher than the 23% of Americans who had read an ebook (according to Pew Research Center in December 2012). It's even higher than the data from Scholastic which shows that 46% of kids in the US had read an ebook.
Of course, this chart also shows that Russians aren't leading the world in buying ebooks; 92% download ebooks from the internet, 36% copy from friends, and yet only 15% buy ebooks.
