I am sure there is - but I don't think CL had the capacity to really 'push' Cox. They weren't rolling out anything better than what Cox had, just comparable, so both were just happily sitting there for years and years not really bothering each other.

Then GFib comes in and suddenly everyone has piles of internet laying around ;)

I don't live there, but I guess it is an oligopoly. They probably offer identical (or very similar) services at similar prices, both making a huge profit. Neither wants to rock the highly profitable boat.
