Final answer:
Cel Animation is a traditional hand-drawn animation process that was used for shows like The Simpsons, although The Simpsons has since transitioned to digital animation methods.
Step-by-step explanation:
The term Cel Animation refers to a traditional animation process where each frame is drawn by hand on a transparent sheet known as a celluloid or cel. Shows like The Simpsons were initially created using this method. In cel animation, artists draw characters and elements on these cels and then layer them over static backgrounds. This allowed for smooth and dynamic animation as each cel represents a single frame in the animation sequence, and when played in rapid succession, motion is created.
However, it's worth noting that the Simpsons has evolved from traditional cel animation to digital methods in recent years. This change was made to speed up the production process and reduce costs. In modern digital animation, drawings are created or edited on computers, which allows for more efficient workflows and revisions.
