How Does Roku Work With Cable TV?

Roku streaming media players do not require a cable subscription to function; however, many cable companies and cable network channels have apps available that allow authorized subscribers to stream content with Roku devices, including Time Warner Cable, ESPN, the History Channel, Showtime Anytime, Fox Now and HBO GO, as of 2015. Some subscription streaming content providers, including Hulu, offer streams of cable TV channels such as Bravo, Oxygen, SyFy and the USA network to members with paid TV subscriptions.
