This is a great hour-long documentary about a technology start-up. It's got all the classic elements: the spark of an idea, the quest for funding, the need for secrecy, the ups and downs of investors, the early products that fuel the drive to the big dream, the disruptive technology winning in the marketplace, and so on. The only difference is this one happened 500 years ago.
The Machine That Made Us is Stephen Fry's telling of the story of the Gutenberg press. It's a good overview of the whole story, inclduding all the technology that went into it. The Youtube link is to a search page because the videos get taken down, but new copies crop up eventually.
