Nice revenue figures there from Mark Coker in Forbes. Even at a low percentage commission charge (and Smashwords charge 10% of retail price for sales through their retail and library distribution network and at their Smashwords store) this would yield quite a chunk of change. Nice work by Mark and his team:

Indie ebooks are starting to sell in a big way. Our revenues are going to be over $12m for 2012, which means that our retail partners are going to sell between $18m and $20m of books. And our books are starting to appear in bestseller lists. Today, when I look at the Apple iBook stats for the US store, Smashwords’ authors occupy five of the top 20 bestselling slots, and one of the top ten, maybe even two today. A year ago, we didn’t have any books in the top ten at Apple. I think that’s really exciting!
