The history of animation, the method for creating moving pictures from still images, has an early history and a modern history that began with the advent of celluloid film in 1888. Between 1895 and 1920, during the rise of the cinematic industry, several different animation techniques were developed or re-invented, including stop-motion with objects, puppets, clay or cutouts, and drawn or painted animation. Hand-drawn animation, which mostly consisted of a succession of still images painted on cels, was the dominant technique of the 20th century and became known as traditional animation.
Today, computer animation is the dominant animation technique in most regions (hand-drawn animation continues to be very popular outside of the US; for example, Japanese anime and European hand-drawn productions). Computer animation is mostly associated with a three-dimensional appearance with detailed shading, although many different animation styles have been generated or simulated with computers. Some productions may be recognized as Flash animations, but in practice, computer animation with a relatively two-dimensional appearance, stark outlines and little shading, will generally be considered "traditional animation" even if it is created on a computer. The first feature movie made on computers, without a camera, is The Rescuers Down Under (1990), but its style can hardly be distinguished from cel animation.
