A new online publishing house, called The Atavist, brings original reporting, long-form, non-fiction stories to mobile readers like the iPad, Nook and Kindle. It was started by a freelance writer for Wired, Even Ratliff, and Nicholas Thompson, an editor at the magazine.
Videos, links, and images are fused with text to create a complete story experience in the demand/digital age. There are only three stories currently available but their website lists a number of writers that they have lined up for upcoming publications. You can check out their site here or read the NYT article about them.
