Re: us isp's Well, note that in many other countries, DSL was the primary internet connection mechanism. Cable networks aren't as common outside the US to begin with, and the US is separate by the fact that cable networks are the largest means of broadband access, not DSL lines.
Cable networks are far better at offering higher speeds to customers than DSL lines, though the reliability and long-term viability of those high speeds is another issue. However, it can't be denied that HFC networks can offer high speeds. This means that buildouts of high-speed fiber networks are not seen as necessary- cablecos won't do it because they already have fiber-coax networks that are fine for what they're doing, and telcos (until recently with VZ) wouldn't have as much demand for their products.
