Maybe it’s different in the US, but in the UK general DSL lines (those offered by British Telecom, for example) are also shared – this is the contention ratio. So in this respect, it makes no difference how your broadband arrives – by cable or phone line – you are potentially sharing with around 50 other people.

What about telephone companies going into the TV/entertainment market? Most comms companies (whatever their origins) have to diversify to stay competitive. I don’t see this as a problem, as you say it drives down costs and improves choice for the consumer.

Good article.
