Which movie was the first feature-length animated film?

The first feature-length animated film was Walt Disney's Snow White and the Seven Dwarfs, released in 1937. While earlier animated films existed, such as J. Stuart Blackton's Humorous Phases of Funny Faces in 1906, these were short films. The development of animation as a medium for feature-length storytelling was a significant leap, with Disney pioneering this format. This paved the way for future animated features and the eventual rise of computer-generated imagery in films like Pixar's Toy Story in 1995.123
