Computer Networks: The Heralds of Resource Sharing - Google Video
Computer Networks: The Heralds of Resource Sharing is a 1972 documentary on ARPAnet. It's a really interesting look back at the initial thinking of computer networks, especially in contract to what we take for granted today. It includes such quotes as "programming is fun." Amen to that. Another excellent quote: "We should deal with information, not the paper it is written on." Watch this, and learn your roots.
