>guess there are a lot of people using Prime for shopping but not using the subscription service for streaming even though they are paying for it?
Yeah, that's what Louise does. Amz doesn't have a recommendation engine. And the content seems to skew more heavily toward the 18-35 demographic.
Netflix has lost some of it's recommendation ranking power since it dropped the 'star' system but it's still possible to be a somewhat passive viewer with its suggestions. Also, the binge-watching is a big deal. I tried to tell Bezos but, NOooooo, he wouldn't listen.
