The broad theme of the episode is the information economy, and it's a whirlwind tour of influential people and tech in the pre-Web 1990s. They focus heavily on Microsoft, Apple, and General Magic, with interviews from key players from each. (Plus, great footage of their headquarters and workspaces.) There's plenty of footage of vintage '90s tech in here, including giant cell phones, Windows NT 3.1, the Newton, General Magic's Magic Cap, Corbis, Encarta on CD-ROM, interactive TV and software agents. Some of the highlights, with screenshots, after the video below.
