James Bamford is a columnist for Foreign Policy Magazine, a contributor to Wired magazine, a documentary producer for PBS, and a bestselling author. He is widely noted for his writing about the United States intelligence agencies, especially the highly secretive National Security Agency. The New York Times has called him "the nation's premier journalist on the subject of the National Security Agency." And in a lengthy profile, The New Yorker referred to him as "the NSA's chief chronicler." His most recent book, The Shadow Factory: The Ultra-Secret NSA From 9/11 to The Eavesdropping on America, became a New York Times bestseller and was named by The Washington Post as one of "The Best Books of the Year." It is the third in a trilogy by Mr. Bamford on the NSA, following The Puzzle Palace (1982) and Body of Secrets (2001), also New York Times bestsellers. In September 2014 he wrote a cover story for Wired magazine based on his three days in Moscow with fugitive NSA whistleblower Edward Snowden, the longest any journalist has spent with him there. In addition, he has written for the New York Review of Books, New York Times Magazine, TheAtlantic, Harpers, Rolling Stone, and many other publications. In 2006, he won the National Magazine Award for Reporting, the highest honor in the magazine industry, for his writing in Rolling Stone on the war in Iraq. He also writes and produces documentaries for PBS, including The Spy Factory, based of his most recent book, which was nominated for an Academy Award in 2010. His most recent documentary for PBS, Cyber War Threat, aired on October 14, 2015.
