It's my experience that so-called "low" or popular culture suffers no lack of attention as a subject for academic discourse---I just wrote a paper on teaching Shelley's <i>Frankenstein</i> using Tim Burton's <i>Edward Scissorhands</i> as an alternate text. Disney's cultural legacy and financial import make the brand an easy candidate for scholarly inquiry. For the sake of grounding this discussion in real-world specifics I did a little fishing this morning in the online scholarly databases. Although I spent rather little time on it (shoulda been working on another project) and I limited my search results to articles with full-text electronic representation (cuz when I find it I wanna be able to *read* it), I turned up a number of interesting examples that ought to make some fun reading (depending on one's definition of fun):

(Incidentally, I only came across a single article specifically about a Pixar film during my admittedly limited and unscientific survey, but it's my general impression that the student researcher would have an easier time finding relevant secondary sources for a Disney paper.)
And it's not as if that's all Disney's good for, academically speaking. The company history, the parks and other real estate ventures (such as Celebration) open wide an array of avenues for inquiry through various disciplines: economics, education, history, anthropology, &c. I came away from this morning's search having donwloaded 20 articles I'll read with more interest & enjoyment that one's average academic research: a couple articles on "It's a Small World" from <i>Ethnomusicology Forum</i>, an <i>Anthropological Quarterly</i> article titled "Walt Disney World: Bounded Ritual Space and the Playful Pilgrimage Center," "Disney World and Posthistory" from <i>Cultural Critique</i>, a circa '76 <i>Drama Review</i> article on Disneyland's "America Sings" attraction (which I never got to see, though I have the audio), a couple articles on Frontierland from western history journals, and so on...including a six-page article published in 1945 written by Walt himself titled "Mickey as Professor." Though dated, I highly recommend Stephen Fjellman's fine book <i>Vinyl Leaves: Walt Disney World and America</i>, an anthropological study which was one of the required texts for <a href="
