Ok. But I really wouldn't trust numbers coming from the same company that produces them. A better gauge would be Nielsen. Roku doesn't even show in the top 10.

Personally I've had Roku from the beginning and never once saw or watched the Roku Channel. But I did look it up now. Looks like all "D" rated films and really old media. They produce nothing and licence and syndicate everything.
