Steven Levy’s new book, Facebook: The Inside Story, is the definitive story – written with unprecedented access – of the company that connected the world and reaped the consequences. Known as 'America’s premier technology journalist' (Washington Post), Levy has been covering the digital revolution for over 35 years. He is currently Editor at Large at Wired magazine, where he was one of its founding writers. During the height of the internet boom, he was the columnist and chief technology correspondent for Newsweek. He also wrote columns for Rolling Stone and Macworld. His seven previous books include the groundbreaking Hackers (1984); Insanely Great (1994), the history of Apple’s Macintosh computer; Crypto (2001) which won the Frankfurt Digital book prize; and In the Plex (2011), the definitive book on Google that was a New York Times bestseller and Amazon’s business book of the year. Earlier in his career, Levy interviewed Bob Marley and found Einstein’s brain, but not for the same story.
