British Pathé was the source for filmed world news, entertainment, and general oddities and information, from the beginning of the 20th century for the next 50 years. Their ‘cinema newsreels’ were shown before the feature in movie theaters in Britain as well as many other parts of the world, and the little rooster logo was iconic. There are now 85,000 historical newsreel clips on every imaginable topic at their site. [Right: screenshot of fascinating (really!) film about wallpaper manufacturing.]
They are free to view online, and can be downloaded with a registration. (Read more about use licensing and restrictions here. )
