According to the Association for American Publishers.
“For February 2011, e-Books ranked as the #1 format among all categories of Trade publishing (Adult Hardcover, Adult Paperback, Adult Mass Market, Children’s/Young Adult Hardcover, Children’s/Young Adult Paperback)”
Just let that sink in a little. #1 in ALL the categories for February 2011.
I’ll post more about this later. But for now, the facts are impressive enough to stand on their own.
