About Us
British Pathé is one of the oldest media companies in the world.
Their roots lie in 1890s Paris where their founder, Charles Pathé, pioneered the development of the moving image.
They were established in London in 1902, and by 1910 were producing their famous bi-weekly newsreel the Pathé Gazette. After the First World War they started producing various Cinemagazines as well. By 1930 they were producing the Gazette, the Pathetone Weekly, the Pathé Pictorial and Eve's Film Review, covering entertainment, culture and womens' issues.
By the time Pathé finally stopped producing the cinema newsreel in 1970 they had accumulated 3500 hours of filmed history amounting to over 90,000 individual items.
Those 90,000 clips are now completely online and free for non-commercial use.
