Based on book sales reported by 85 publishers to the Association of American Publishers.
Ebook sales: $31.9 million, up 261.2%
Interesting highlights from the rest of the figures:
Adult hardback fiction: $55.6 million, down 8.1%
Adult paperback fiction: $103.2 million, up 0.8%
Adult mass masket fiction: $56 million, down 0.5%
Main losers over the year were religious books, children/YA paperback, professional and scholarly, and children's hardcover.
Now, it seems to me that this means that publishers should (1) take ebooks really seriously and (2) stop claiming large losses due to piracy.
But I rather doubt that they will.
