Yes, Disney's reputation in themed design. That was clear from the context of his post, and the fact that we are actively participating in a discussion forum dedicated to Disney's work in themed design. I would imagine that he's familiar with the fact that Disney as a company didn't suddenly exist upon the opening of Disneyland.
Do you really need people to constantly point out to you when they're specifically talking about the theme parks and not the media conglomerate when they mention Disney here on the Disney theme park website?
Like, come on.
