The Disney Company was built on selling art. Sure, their films (and music, and theme parks, and video games, and so on) are always designed and optimized for the purpose of entertainment. Sure, they always think about their bottom line and expect to turn a profit by appealing to the masses. And yet, their creations always strive for emotional resonance, or thematic power, or pushing the boundaries of the chosen medium — or some combination. This is a way of saying it is art.
Of course, another way to define “selling art” is to find or commission artwork from other people and sell them in a gallery. Here is some information about Disney’s own take on the concept: Wonderground Gallery.
