Within the time period described, cave paintings were established as the earliest form of animation, originating in France. Early animation devices like the phenakistoscope and zoetrope used sequential images to create the illusion of movement. Émile Reynaud developed the Praxinoscope and Théâtre Optique, projecting animated cartoons. Winsor McCay's Gertie the Dinosaur was among the first animated films shown in cinemas. The development of technologies like cel animation, sound synchronization, and color allowed for more advanced animated films. By the 1980s and 1990s, computer animation had replaced traditional hand-drawn animation, beginning with films like Tron and Toy Story.
