That's a decision between the cable provider and the company to come to an agreement. Not sure why there's not one there.
A common misconception, and this doesn't make much sense to me either, is that Time Warner and Time Warner Cable are the same. They are actually completely separate companies. CN is part of Turner which is part of Time Warner, but since TWC is separate they can still have whatever agreements they want.
i just meant that literally everytime i try to use something like this (a site, an app, whatever) that makes you log in with your cable company info time warner cable is NEVER an option. things like this make me consider getting rid of cable all together.
