US eBook sales race past 20% of publishers’ revenues

I’ve just tweeted these stories, but my jaw is still hanging loosely from its hinges, so I thought I’d better provide the links here:

Over 20 percent of Random House US sales are digital

Over 20 percent of Hachette’s US sales are e-books

Both stories come from, which also reports that Simon & Schuster is at 15% in the US, HarperCollins 12%, and Penguin worldwide 14%.  Not evolution, but revolution
