Part of it is not worrying about advertisers. It's why shit on HBO is so much more interesting than other networks.
Thought of that while reading this too: Asking "who's the customer?"
It turns out asking "who's the customer?" is a great way of thinking about when certain companies or industries do things that aren't aligned with good customer service or user experience.
The customer for network TV shows isn't viewers. The customer is the advertisers. The viewer is just a means to an end. AKA "if you're not paying for the product, you are the product."
