Roku is one of the bigger players in the spectrum, selling hardware that enables households to ditch cable and satellite for a never-ending swarm of streaming TV apps. It gained significant market share against its competitors — Apple, Amazon, Google and Nvidia — by positioning itself as an agnostic player in the space: Everyone can make an app for Roku, and lots of companies do, including those who sell similar hardware devices (Apple, one of the last holdouts, launched an Apple TV app on Roku late last year, making movies and TV Shows once purchased through iTunes available on non-Apple television hardware for the first time).
