Internet Archive: Prelinger Archives

Rick Prelinger's Video Archives has been made available for download. It includes mostly stuff from the 1940s to the 1970s, including 'social engineering' shorts on hygiene and dating (like they goof on in MST3K), the infamous safety films of the 'Blood Runs Red on the Highway' sort, documentaries, TV commercials, government educational films and propaganda, Duck and Cover, the Tacoma Narrows Bridge disaster, the Hindenburg explosion and lots more. Check it out, it's Jam Handy!
