Municipal cable companies
I'm working with a municipal cable company in my spare time. We are able to offer broadband at 80% of the price from the major commecial cable company. And we are making so much money that we have been able to replace most of our cables over the last 5-6 years.
And we are not that big - 5600 cable TV subscribers and 4200 internet subscribers.
The major problem/issue why no more are doing this is that it looks like a lot of work....
It really is not - it is not easy, but not that hard either.
