The increase in ebook sales were made by Jeff Bezos in a news release announcing Q4 2012 and Full Year 2012 earnings.
“We’re now seeing the transition we’ve been expecting,” said Jeff Bezos, founder and CEO of Amazon.com. “After 5 years, eBooks is a multi-billion dollar category for us and growing fast – up approximately 70% last year. In contrast, our physical book sales experienced the lowest December growth rate in our 17 years as a book seller, up just 5%. We’re excited and very grateful to our customers for their response to Kindle and our ever expanding ecosystem and selection.”
