The challenge here is that the larger telecom companies (AT&T, Verizon) are required by law to sell their loops to other carriers, but there is a lot of CAPEX needed even with the fiber/copper look. It costs around $1000 per subscriber to bring a broadband TV service home even from the neighborhood (connecting from neighborhood to home and all the equipment in the home). This high CAPEX is a barrier for new entrants in this market.
Another reason why US is behind is that the US Federal Communications Commission (FCC) is not allowing the telecom companies in US to charge users based on their tiered internet usage. Therefore, price per mbps is flat no matter how much bandwidth you use. On the other hand, European telecom companies are allowed to charge extra for higher bandwidth usage.
Once these two barriers fall (cloud based home TV management and tiered pricing) there will be more competition in US.
