it's the internet of course it is. it affects culture in the way the center does: how we think, what we do, what we talk about, what we wear, etc. i can easily find people who don't watch tv, but good luck finding those who avoid the internet ("the new rebellion")
Of interest, too, is that probably THE central sub-medium of the internet is web video, which is film. The internet ate everything, but its heart and lifeblood remains film. People are constantly watching short form content, they're just not the type of content we who grew up with capital-F Film culture hold dear (ie. feature-length, well-produced, etc.). But they could be if this is what people wanted. This is the true democratization of the form, the thing Coppola talks about at the end of
Hearts of Darkness. We've now seen what the little fat girl in Ohio makes ... and it's Musical.lys and vlogs and the Shiggy challenge. Whether or not we like it, this is filmmaking -- sans professionalism.
I'm not sure, however, that Coppola's closing remark, that this is when film will finally become an art form, has been realized. Certainly, I don't think there's been much in the way of web video that compares with the best of cinema on the basis of artistic merit. At least I haven't seen it if it's out there. But this is not so much an internet/film problem as a democracy problem.
