"Time Warner Cable operates in 29 states, but thanks to the old system of regional and municipal cable monopolies, Comcast and Time Warner Cable don't compete anywhere."
This is your state government(s) shafting you. The states created laws which allow cable monopolies. Local governments collect a franchise fee on the gross revenue of the cable companies operating within their boundaries. In the eyes of local government, less competition means higher prices which means more tax revenue (without voter feedback). Local government passively discourages competition through regulations, filings, public meetings, disclosures, insurance requirements, etc. Some local (and state) governments *actively* discourage competition.
