How things 'clacked' for Kodak at Expo

Q: How did people first learn about film?

The very idea of film was first presented to the public at the 1889 Paris Expo by George Eastman.

The inventor stumbled upon the discovery of film a year earlier when his camera shutter clicked, making a loud clacking noise that sounded like "kodak". The sound translation was thus chosen for the name of the now widely popular household film brand Kodak.
