I think you and the person above you are underselling Netflix's innovation. Yes it's true, they mostly solved the problem of streaming video over the internet, and most changes there are incremental.

But they are currently innovating massively in machine learning and other data analytics. They are also innovating in "Hollywood tech".

Hollywood still uses old tech to move from capturing the actors performance to putting it in front of viewers. They mostly still track their assets with Excel (or on paper!).

Netflix can get a show from filming to viewers a lot faster than most of Hollywood can.
