Cartoons can be created through both traditional animation and computer animation techniques. Traditional animation involves hand drawing each frame while computer animation uses 3D computer graphics. Some of the earliest animated cartoons date back to the late 1800s and early 1900s. Popular animation studios that produce cartoons include Disney, Warner Bros., Hanna-Barbera, and many others. Different styles of cartoons also emerged such as anime which originated in Japan with manga-influenced stories.
