Hmm I see how this could be a problem but seriously, cable internet is like 30-40 dollars, for only having access to facebook, youtube, cnn, and some other large sites like that it would need to be like $5 a month lol...
Secondly, you are missing the related trend... TV views for popular shows are going DOWN! Internet episodes are going through the roof!!!! If anything people are ditching their TV service for internet only now that you can get cheap high speed and use an HD tv for a monitor, or buy a large LCD monitor like 24 inches or something.
So I don't think this is going to be a problem.
