I would rate his theme parks and full-length animated features as his most significant accomplishments. The others that were listed are impressive, but most of them were technical achievements that would have eventually come along without Disney's contributions. In making a full-length "cartoon" in Snow White and designing a revolutionary type of theme park, Disney went against traditional ideas in those industries and broke new societal ground. Is it coincidence that even today, people associate his company with animated films and theme parks before all of the other things they do?
