Rhetorical studies of public-access cable?

So, I'm sitting here watching -- for some reason -- Drinking with Troy and Ian, a public-access cable television show. It consists of a couple of guys who look to be in their early twenties sitting in front of a camera and drinking. That's it. In the space of forty-two minutes, they've downed seven shots of Jägermeister. I'm nauseated just witnessing it (assuming it's real Jägermeister).

But it occurred to me: I've listened to podcasts that are kind of like this, and any substantial study of citizen media (which is a big part of my research agenda beyond my dissertation) ought to look at public-access cable. It seems that there's a stereotype that people who make use of public-access cable are political wingnuts and/or just plain weirdos. Think about the Saturday Night Live spoofs of it (and, of course, of Jimmy Fallon's famous character, Jared at Hampshire College, who has the web show from his dorm room). If anyone knows of any studies of public-access cable, doesn't matter what discipline, will you please let me know here or via email?
