The ownership ? gets very confusing. Below is the result of a Google search, I just ran.
Every link in that search shows TW is the owner via TBS.
Cable News Network (CNN) is an American basic cable and satellite television news channel owned by the Turner Broadcasting System division of Time Warner.

I was thinking TWC was split with Charter buying their CATV assets and now AT+T is trying to buy their internet and ISP assets.
