Hello mimmib9816. We appreciate you visiting and posting on the Xfinity Forums. To get CNN, you would first have to subscribe to a cable TV package that comes with that channel. If you need help reviewing the available TV packages and offers, I can help with that. To get started, please send me a private message and include your full name so I can assist you.
