From Wikipedia:
This day commemorates the first public performance of Charles-Émile Reynaud's Théâtre Optique at the Grevin Museum in Paris, 1892. In 1895, the Cinematograph of the Lumière brothers outshone Reynaud's invention, driving Émile to bankruptcy. However, his public performance of animation entered the history of optical entertainments as shortly predating the camera-made movies. In recent years, the event has been observed in more than 50 countries with more than 1000 events, on every continent, all over the world. IAD was initiated by ASIFA, International Animated Film Association, a member of UNESCO. During International Animation Day cultural institutions are also invited to join in by screening animated films, organizing workshops, exhibiting artwork and stills, providing technical demonstrations, and organizing other events helping to promote the art of animation. Such a celebration is an outstanding opportunity of putting animated films in the limelight, making this art more accessible to the public.
