The biography of Apple co-founder Steve Jobs written by Walter Isaacson has been Amazon's biggest-selling book of 2011, the online retailer announced.
The accomplishment is impressive since the book did not start selling until late October.
Despite its hardcover success, the biography of Jobs ranks No. 3 on Amazon's Kindle bookstore.
The Kindle bestsellers so far are "Hunger Games" by Suzanne Collins and, at No. 2, "The Litigators" by John Grisham.
