Robert X. Cringely, the pseudonym of writer Mark Stephens, hosts this PBS chronicle of how a Pentagon research project turned into a global network. The film runs from ARPANET's Cold War origins through the rise of email, the personal computer boom, and the dot-com gold rush of the late 1990s, with the people who built each piece telling their own part of it: Vint Cerf and Bob Kahn on designing TCP/IP, Marc Andreessen on writing the Mosaic browser that made the web usable, and venture capitalists explaining how garage projects turned into public companies overnight. Interviews are shot plainly, mostly talking heads intercut with contemporary news footage of stock tickers, server rooms, and early web pages, letting the subjects argue their own version of who deserves credit. Cringely's narration keeps a dry, skeptical edge, treating Silicon Valley's self-mythology as material to test rather than repeat. Three hours long and produced right as the internet was becoming a mass medium, it works as both a technical origin story and a document of the moment before anyone knew how large the thing would get.
