My guess is that internet providers will employ one of the oldest economic tricks in the book: subdivision -- just like buying a 40-acre farm for half a million bucks, then subdividing it into 320 single-family lots and selling them for $50,000 each.
So how would that work? Sort of like cable works now:
-- Basic internet -- email and unlimited access to your ten favorite sites (facebook, twitter, etc), plus the provider's very limited search engine -- $50 a month
-- Family plan -- Same as above, except no xxx sites -- $75 a month
-- Google Basic - Same as Basic, but 25 Google searches a month - $100 a month -- family plan supplement $25
--- Google Plus -- Same as basic, but 100 Google searches a month -- $150 a month, etc.
-- Google unlimited (that is, the same we have had up till now with net neutrality) -- $200/month, etc
It can be sliced and diced all different kinds of ways -- premiums for streaming, for gaming, for shopping....
Watch your wallets!
