They haven't "created an artificial monopoly around their persona". You've just created an artificial justification around your actions.
You're also not "basically forced to watch them".
HBO operates with a margin of 33% (1.7Billion income on 4.9 Billion of revenue). That's healthy, but it isn't "totally insane". There isn't much room to spare before they'd have to sacrifice quality. That'd be quite sad, considering the last decade is generally regarded as a golden age of TV.
I've watched probably more than 8,000 episodes in my life. Not because I wanted to keep up with anything (no external motivation), simply because I was addicted to TV shows (great ones, no regrets).
Now I don't watch TV anymore, or ever so rarely. I've converted the time to reading. It changed my life in dramatically good ways —pun very much intended. There's a time for everything, and quite frankly after some time it's like you've watched it all, you could predict plots and even lines (sometimes it feels as though all authors just get inspired from their peers and much of the writing/directing feels recycled).
There's no "keeping up to date" with pop culture imho, at some point it becomes anthropological. You just overgrow pop culture beyond a certain amount of experience. You could actually produce it for that matter. As it relates to the medium, thus technology, I'm thinking it will evolve once again with VR/AR/etc.
