Connections, the Day The Universe Changed, The Secret Life of Machines, and Beakmans World. TLC before it sucked was awesome.

One of the greatest shows ever made

That was my favorite show when it was on. He’d start every episode saying what he was going to connect to what (e.g., the development of modern telecommunications to the invention of the stirrup). And then he’d wander around historical locations giving amazingly fascinating commentary and explanations of historical events.
