If you haven't yet heard of Roku––a set-top device that allows you to stream TV and movies on demand to your television set––you probably will soon. The company has announced its service will be built into more TV sets in 2015, continuing a collaboration with TV manufacturers that began in 2014. By integrating its service into TV sets, the company makes access easier and eliminates the need for a separate remote. The company will continue to produce its set-top models.
