Time Warner (Spectrum, after Charter buyout) now has TWC TV thru devices like Roku. Been using Roku boxes for years. Not a "cord-cutter" yet, though.
It works well. You'll need enough Mbps (I've got the 50 Mbps) and you still have to be a subscriber.
"TWC TV® app -- not just for phone and tablet
Several people can watch different shows on different devices at the same time. Sign in to the TWC TV® app on devices such as Kindle Fire, Roku, Xbox and Samsung Smart TV.
Kindle Fire HD & HDX | Roku | Samsung Smart TV | Xbox One | Xbox 360 "

The real issue, in my view, is "broadband" v. "cable". Different Fed. and state laws/regulations stifle competition.
