Roku streaming devices partner with channels to provide a large selection of free, subscription and rental channels on demand. Paid or premium channels are available through Roku.
The Roku Channel Store lets users add or remove channels. As of March 2015, free channels include YouTube, TED Talks, NASA TV and Free Speech TV. Premium channels vary in price. They include Hulu Plus, Netflix, History Channel and Now TV.
All content is streamed, which means that it is delivered to a TV through the Internet. Roku has been in existence since 2002. The company's streaming players are set-top boxes used for the delivery of content over the Internet.
