Some of the films available come from licensing deals with studios like Lionsgate, MGM and Sony Pictures Entertainment while others are sourced from other Roku channel publishers such as American Classics and Popcornflix. Some films you can expect to find at launch include Ali, The Karate Kid and Legally Blonde as well as hundreds of others from classics to blockbusters.

There are no added fees for the channel, which is supported by ads. But Roku says that there are half as many advertisements as there are on traditional television channels.

Roku, which just recently filed for its IPO through which it seeks to raise $100 million, has over 15 million active accounts and its devices account for 37 percent of all streaming media players used in the US.

The Roku Channel starts rolling out now and should reach all devices in the coming weeks.
