Many U.S. cities have gone after municipal fiber solutions, the problem is the existing govt. mandated monopolies are blocking them in court with near unlimited legal budgets, lobbying groups and fake 'grass-roots' campaigns. Very few have managed to build out the networks, and many that tried have been tied up in courts for years (still are). I dont have any real stats but judging from news stories over the last few years I would guess 90% of these efforts fail due to the existing corruption in US business and government.
Sure we have, it the web cam in the TWC board room. They repeat the show at every board meeting.
