One of my favorite bloggers (and only the inventor of the frigg'n web browser) Marc Andreesen has a post about a video on the secret history of the Silicon Valley. It is a long video, but well worth it.
It was a Google Tech Talk video from Steve Blank late last year. I'm currently consulting on a project for a war museum and so the content of this video, how the CIA/NSA and Fred Terman 'really' built the silicon valley, is really fascinating.
