The document provides a history of animation from its earliest origins in paleolithic cave paintings through key developments over time. Some of the earliest animation devices included the magic lantern in 1650, the thaumatrope in 1824, and the phenakistoscope in 1831. Important later developments included Winsor McCay's use of keyframe animation in Little Nemo and the first full-length cel animated feature, Snow White and the Seven Dwarfs, released by Disney in 1937. Modern milestones included Toy Story in 1995 as the first full-length CG feature and Avatar in 2009 which utilized new camera technology allowing live action and motion capture to be viewed simultaneously with CG.
