The biography of the late Apple founder Steve Jobs has sold 379,000 copies in the United States in its first week.

The book, called simply Steve Jobs, is the authorized biography of the former Apple CEO, who died just under one month ago after a long battle with cancer. Author Walter Isaacson was given authorization to write the book after Jobs gave his full cooperation to the project in his final days.

Isaacson has used information from over 40 interviews with Jobs. After only six days of sales, the Jobs biography is already the 18th-bestselling book of the year, according to BookScan's figures. Simon & Schuster had decided to move up the book's publication by a month after Jobs' death on Oct. 5.

Segments of the biography include Jobs’ personal opinions of rival Bill Gates and his Microsoft Corporation.

Jobs told Isaacson “Bill is basically unimaginative and has never invented anything, which is why I think he’s more comfortable now in philanthropy than technology. He just shamelessly ripped off other people’s ideas.”

The book instantly rose to the top of’s pre-order list and many in the literary industry expect the book to emerge as Amazon’s top seller for the entire year.
