I love that these premium channels are starting to go streaming for a direct cost rather than requiring cable packages. The future is starting, finally.
I'm not sure it's going to make much difference price-wise though, cutting out a middle-man doesn't guarantee lower prices, it could just mean better margins for the content creators. And certainly that's exactly what they'd want.
Yes, it's great having on-demand content rather than packages including lots of 'filler', but we'll probably end up paying more for the premium content. You want this, you need a HBO Now subscription. A Netflix-exclusive show? You need a Netflix subscription too. The more things change..
