We all love a Disney film; the originals like Dumbo, the more up to date Pixar films like Toy Story, or just good ol' favourites such as Beauty and the Beast. Disney have been accused of many things since making these children's favourites; institutional racism, hidden sexual meanings amongst others. Speculation suggests that the new Finding Dory film features a lesbian couple, which, in wider contextual terms, clearly shows that the institution is responding to cultural and sociological change, especially with the legalisation of gay marriage in many countries. Is Disney responding to Market Imperialism? Has the audience made it clear that they want to see fairer representations of what are considered to be niche social groups in the media - is this Disney's response to it? If this is true, this is certainly an interesting case study to write about!
This could also like in with Orange Is The New Black which has also broken boundaries in terms of a homosexual presence in the media, and more importantly one of which that has been deemed acceptable. You could also link these examples with Queer theory too.
