Amazon Wants to Get Into the Used E-Book Business -- Or Bury It | Wired Business | Wired.com

E-nightmare for publishers?

"Last week, Amazon patented a way to sell “used” e-books, music, videos, apps and other “digital objects.” The marketplace described in the patent would let such exchanges take place by cutting off the seller’s access to a piece of digital content once the buyer paid.
If the world’s largest online retailer opens the door to digital yard sales, the result could upend the business models of already struggling book publishers and record companies, not to mention thriving digital marketplaces like iTunes, Google Play, and Amazon itself. That is, if Amazon ever really intends to make used digital sales a reality."
