Anything from the 90's has already been replaced or has long been fully depreciated. The simple fact is the telephone operators resisted at first and then largely failed to be competitive in the consumer access space.
This allowed the content guys "cable" to get in they game. They got everything to the "good enough" stage for major market segments, choked out the competitive offerings (the telcos and mom and pop ISPs) and have stagnated ever since. Mainly because they needed time to get their IP-VOD offerings up to industry par so they can protect their content distribution middle man revenue bonanza before allowing "cord-cutting" to be totally viable for most. Now that digital cable offers most of the on demand flexibility and DVR functions people seem to want they can lever their existing content agreements to ensure that stays the best deal. They don't have to worry about NFLX eating their lunch.
