For computers, the best one IMHO was a PBS documentary called Triump of the Nerds (invidio.us) by Robert X. Cryngely. He made a sequel called Nerds 2.0.1 which was aright. Another great blast from the past (mentioned in Triumph of the Nerds) was The Mother of All Demos (youtube.com).
Here's a few more conspiracy ones that will rattle you a bit:
1) Challenger Disaster (invidio.us).
2) Is Nuclear Power as Dangerous as they say? (archive.org)
3) Are Nukes Even Real? (archive.org)
There's more, but I don't want to overwhelm you. What do you know about the Kaballah? Protocols of Zion?
