After debuting on iOS and later expanding to web browsers and Android, Time Warner's live streaming TV service, TWC TV, may soon be made available for Roku set top boxes. Citing an unnamed source, Engadget claims that company representatives are currently being briefed on the software, but cautions that a public rollout could still be several months away. With Comcast's Xfinity app launching on the Xbox 360 last month, potentially reaching millions of new users via Xbox Live, the heat is on for Time Warner to offer its streaming service on more devices.
