An interesting figure from Kindle Nation Daily:
Total first-week ebook sales for Steig Larsson's instant bestseller The Girl Who Kicked the Hornet's Nest amounted to nearly 30% of all units sold, according to a report today from Publisher's Marketplace... "Knopf Doubleday spokesman Paul Bogaards says their internal figures show an approximate first week sell-through of 425,000 units--which includes 125,000 ebook editions."...this translates into a 29.4 percent ebook share of the title's total sell-through, which would be by far the largest percentage yet reported for ebook sales of a major trade bestseller.
Yes, this is only one book. But how long before it's most books?
