Most of us reading on the blue lived through at least a portion of it. Forty-plus years of tension between the world's two superpowers and their allies. That's right: The Cold War. Then, they made a documentary. Aired on CNN in 1998, and never released on DVD, the 24 episode, 20 hour series features tons of archival footage, along with many interviews with individuals directly involved at some of the highest levels. You might not be able to see it on DVD, but you can watch the full series on Youtube, starting with Part 1: Comrades (1917-1945).
More than 600 Universal Newsreels at Internet Archive, both whole and partial reels (the same collection, with a few more newsreels is also on YouTube but it's in lower quality). Newsreels were short collections of current events that ran before feature films. They ran from the start of the film era up into the 1960s. This collection goes from the early 30s through the mid 60s. Here are a few interesting ones: Eleanor Roosevelt tells a joke, 1935 car industry workers strike, Australian who was orphaned in China and raised by Chinese parents returns to Australia, FDR inaugurated, Enos the chimpanzee goes into space and returns to Earth, Vietnam War protest marches in New York, San Francisco and Rome, Busby Babes plane crash, Gagarin hugged by Kruschev, Truman brings the funny, Seattle be-in and Nuremberg trials.
