Not quite as highbrow, but Pixar stuff, particularly the earlier movies, manage to have jokes that work for kids and their parents. It was much appreciated.
The reason they were produced from the 1930s to 50s was to be run in movie theaters before the main picture. Since they would run before different kinds of movies they had to entertain both kids and adults. Some of the humor in those cartoons clearly went way over the kinds heads.
It was only later that they were bundled as TV shows for children.
