It's worth mentioning that not every jurisdiction in the U.S. regulates utilities in the same way. Some are strict; others are lax. Look at Texas.
My trash collection, strictly speaking, isn't a utility. I pay the township where I live a monthly fee and they contract with a commercial waste hauler. I imagine I get a price break compared with contracting on my own, since the township can guarantee almost 16,000 households as customers (minus apartment dwellers and condos and perhaps some other types of housing).
There are areas where cable TV isn't a monopoly. IIRC my mother can choose between two providers. Ok, not far from a monopoly, but there's still a tiny bit of competition.
An awful lot of people get their Internet connection via those regulated monopoly cable providers.
