From Variety:

British Pathe, the U.K. newsreel archive company, has uploaded its entire 100-year collection of 85,000 historic films in high resolution to YouTube.

The collection, which spans 1896 to 1976, comprises some 3,500 hours of historical footage of major events, notable figures, fashion, travel, sports and culture. It includes extensive film from both World War I and World War II.

Naturally, I looked for some videos about smog, air pollution, and the environment. The Archive doesn’t disappoint. There are pieces called “The Smog Menace”, “Smog Detector”, and a documentary called “Guilty Chimneys” (part 1 + 2, part 3).

There’s a lot of fascinating stuff in the archive beyond smog and air pollution. Pretty cool.
