There is a fine little article here about Cox Communications and what they are doing to delivery better internet and entertainment services than ever before.  In short Cox is taking many different approaches to improve bandwidth effeciency along all of their communication lines that will in turn allow them to provide to their customers better service than ever before.  They have already taken a major step in the right direction by having over 70% of their Markets networks upgraded to 1Ghz speed.  This is going to allow Cox to bring 25Mbps downstream and 4Mbps Upstream internet connection.  Cox has also recently added Food Network HD, HGTV HD, CNN HD, and Animal Planet HD to their HD Channel line up.  Can't wait to see what other kind of improvements are on the way with switched digital video, mpeg 4, and Cox's own 18,000 Dark Fiber backbone all in the works.
