"Animated drawings were introduced to film a full decade after George Méliès had demonstrated in 1896 that objects could be set in motion through single-frame exposures. J. Stuart Blackton's 1906 animated chalk experiment Humorous Phases of Funny Faces was followed by the imaginative works of Winsor McCay, who made between four thousand and ten thousand separate line drawings for each of his three one-reel films released between 1911 and 1914. Only in the half-dozen years after 1914, with the technical simplifications (and patent wars) involving tracing, printing, and celluloid sheets, did animated cartoons become a thriving commercial enterprise."
