Cable companies make their money selling TV, internet and in some cases phone service. If they lose enough revenue from Netflix, Hulu, etc and people start using more bandwidth, they are going to raise their rates, just like the cell companies.
That's the issue, though: conflict of interest. It's time these companies were broken up in the interest of competition. Comcast the content provider should be separate from Comcast the internet provider. We are relying on companies to deliver content that competes with the content they themselves are trying to sell. My Netflix looks terrible even though I have a fast connection. Why? Because Time Warner and Netflix are not playing well together. Why? Because ultimately Time Warner is not pleased to be delivering third-party content that keeps me from needing an expensive cable package.
And as far as paying for bandwidth, fine. We pay for electricity and everyting else we use based on usage, so why not this? As long as it's a LEVEL playing field with true net neutrality, bring it on. I'm fine paying for X GB a month if *I* get to choose what to do with it and Time Warner doesn't get to monkey with what they think I should get at what speed. Again, internet should be a utility. As long as it's regulated like other utilities.
