A video produced by Reveal from The Center for Investigative Reporting that examines the U.S. surveillance industry has been honored with an Emmy Award from the San Francisco/Northern California chapter of the National Academy of Television Arts & Sciences.

The Secret History of American Surveillance, which won in the informational/instructional segment category, traces the surprising origins of the modern surveillance state and examines how beholden the government has become to private corporations that handle our sensitive information. While surveillance technology has evolved and changed over time, our research unearthed several little-known and surprising facts, with uncanny ties to modern events.

The story was directed and produced by Ariane Wu and executive produced by Amanda Pike with motion graphics by Richard Levien.

The video is part of Reveal’s online project Post Script, a three-part series examining how some of mankind’s brightest ideas wound up taking an abrupt turn from their original design.
