Not sure about other states but it is like water or electricity. You will get cable or ADSL or WiFi(EDIT: it might even be fibre) provided by state and you need to only get ISP.
In many of those rural areas of the U.S., people have their own personal well for water out of the ground, so water may be a bad example, unless you are saying that their is some way to dig into the ground and tap directly into some high speed internet reservoir?
