Cox dropping At Home

I just read an article on the NYTime site about Cox and Comcast may drop
the At Home internet service.
I was under the assumption that @Home was owned by cox and they
controlled all the servers.
So now I'm quite confused. What exactley does cox do? They provide
cable tv and what? No internet services?
