The Machine That Changed the World: Great Brains

the longest, most comprehensive documentary about the history of computing ever produced… a whirlwind tour of computing before the Web, with brilliant archival footage and interviews with key players — several of whom passed away since the filming. Jointly produced by WGBH Boston and the BBC, it originally aired in the UK as The Dream Machine before its U.S. premiere in January 1992.
