At my house, we are experimenting with a new rule to fight internet addiction: no internet connection between 10pm and 7am. It is very easy to implement since it's just a matter of switching a button. It has the immediate consequence that we get more sleep. It's a measure of how much we rely on the internet that it has taken some discussion and required an effort of will.
I suppose that that could be embedded in Verizon, Cox, and other internet service providers. They could give us an option to have a subscription that excludes nights and Sundays, for example.
