Municipal broadband has been a success for those communities that have begun offering service. It is no surprise. Historically, local government has always corrected market failure by providing essential services. The driving force for efficiency in these networks is not profit maximization, but public service. The money saved through cost reductions stays in the community. Public networks have increased broadband competition, not reduced it, and they have resulted in lower prices. The propaganda maligning municipal systems is nothing more than industry-sponsored folklore.
Comcast Brags About Lack of Broadband Competition in America
The next time you hear someone claiming that the broadband market in the U.S. has plenty of competition, remember this statement from Comcast CEO Brian Roberts.
And so each of the last two years, we have had modest increases in the cost of the broadband service, and yet we've had tremendous sales. We're 33%, 31% penetrated. We hope someday all of America has broadband. So the goal would be 100 or 90 [percent take rate]. We have one competitor.
And over the course of that 2011 interview [pdf], Roberts makes it clear that he (correctly) regards DSL as a very weak competitor. The only problem Comcast has is in those few markets where they overlap with Verizon's FiOS (or, left unstated, in areas like Chattanooga where the community itself has built a technologically superior network).
