After launching on Android and iOS last month, the Roku Channel, the streaming company’s free, standalone TV service, is now available on Amazon Fire TV devices, the company said in a blog post Thursday. That includes Fire TV streamers and also Fire TV Edition smart TVs and soundbars.
With 115 live channels and a library of more than 100,000 ad-supported TV and film titles, the Roku Channel includes news content from ABC News Live and Reuters, kids content like Teletubbies and KidzBop, lifestyle content from Bon Appetit, and recent additions like The Lego Channel, HappyKids.tv, Maverick Black Cinema, and new Spanish-language entertainment options. That lineup puts it in the same league as free services like Pluto TV and Xumo TV, which rely on older, lesser-known content instead of the traditional live channels that come with cable TV.
