Consider the basic streaming transaction: consumer tunes in to watch an episode of their favorite show on some streaming service. Several companies are involved in the transaction: the streaming service, the broadband provider, and the content company that made the show. But the consumer doesn't really care about any of that, he's willing to pay $X for the experience of watching that episode.
How that $X is split up amongst the companies in play is the subject of a lot of legal wrangling. Each party has an incentive to try and turn the contributions of the other parties into a commodity. The streaming service and the broadband provider have an interest in weaker copyright protections, so the content company has less leverage. The streaming service and the content company have an interest in net neutrality, because that prevents broadband companies from differentiating their services from each other, and forces them to compete only as "dumb pipes."
It's not clear what the "proper" division of that $X should be. Arguably the content creation is the least fungible from the consumer's point of view. If they want to watch "House" that's what they want, not some substitute. The broadband provision is arguably the most technically complicated and the one that involves the greatest capital expenditure. Distribution is, in my opinion, relatively simple. Computing power and commercial bandwidth are commodities thanks to AWS and the like. So all that differentiates Netflix from Hulu from Youtube is the software. The software isn't easy per se, but it's easier than making a blockbuster movie or building a fiber network. That's why streaming sites are a dime a dozen but it takes the likes of Amazon or Netflix to even attempt to compete with NBC, etc, in developing AAA content.
That's almost certainly why Netflix is getting into the content business, and why Youtube has always been in the content business (through user generated content). That's what's hardest to turn into a commodity.
