I stand corrected about cable networks. But my thesis that allowing one-sided broadcasting of views still stands: it insulates people from contrasting views and makes them uncomfortable with having those views challenged. I'm not suggesting we go the route of state run media, but state regulation of media may come about thanks to what happened yesterday.
Seems to me, at least on cable, people are only as insulated as they want to be. They can always change the channel to one of any of several hundred others. There are more views being expressed on cable than were ever allowed on the airwaves during the fairness doctrine era.
Some of those channels are spewing hateful horseshit, but with dozens of channels to choose from, you can't blame the medium for people being insulated. They keep the dial tuned to Fox News because they like it.
Unfortunately I don't think it's that black-and-white. Fox News is a small part of the information bubble, which includes other sources like YouTube, Facebook, Twitter, etc. And there's evidence that social media addiction is real. So the content is feeding into a positive feedback loop that prevents people from regulating their ability to tune into something else.
This doesn't absolve the viewers from responsibility, but it also doesn't place it entirely on their shoulders.
