Regular Google isn't really meant for scholarly research, so it's not that surprising that you didn't find much that way. If you can find a wikipedia page that's relevant, you can scroll down and look at the sources they used and pursue those. You should try searching Google Scholar. Several articles pop up when I search there. I don't know if they're what you're looking for, but they'd be worth looking at.

You should also be using your school's library/librarians to help you find sources (and help you learn tips for doing scholarly research). Does your school have a subscription for JStor? If so, you would have access to even more articles that could be relevant. For this topic, I think articles would be your best bet, especially if you want more current research.

I would also be wary about movies and website articles. Not all of those are "scholarly" if you know what I mean. They could work if you want to cite their author's opinion, but be aware what is opinion and what is actually research. Also always be aware what is appropriate for your paper/research.

I think it's a good topic though. You just need to change your research tactics to yield more results.
