Amazon automatically deleted certain copies of George Orwell's 1984 and Animal Farm from customers' Kindles. But many facts were left out of this media frenzy, namely that the ebooks were essentially pirated copies sold for 99-cents by a company that had no rights to the material. Amazon was able to remove the titles because the Kindle is configured to automatically sync up with the user's Bookshelf via the electronic book reader's WhisperNet wireless service. When the company removed the unauthorized books from customers' accounts, they also disappeared from the Kindle. Amazon then delivered a cryptic e-mail about what happened.
