If you ever had a friend growing up whose family was devoutly religious, you might have seen something similar: They run in totally different circles, all their friends are from their church, they take their kids to totally different movies, listen to totally different music. Can't talk sports with them because they literally can't name a football team. No culture overlap at all. Totally siloed off in their own world. That's what's happening with all this personalization and alternative news sources now, but instead of a small group of very religious people, it's 30-40% of the country!
The Adfontes Media Bias chart uses a two-axis system, plotting accuracy against bias, and inevitably ending up with most sources on an inverted-V shape: https://adfontesmedia.com
Unfortunately, Pew's list is not consistently updated like the Adfontes chart and other media-bias checking sites.

The web and partisan cable news channels have long since done away with that commonality. It's dead, buried, and cold in the ground. That's why it feels like one side of the political spectrum is living in the world of Fox News, Newsmax, OANN, and so on, while the other side is living in the world of CNN, MSNBC, Huffington, Vox, and so on.
There are some very good attempts [0] to make media bias more visible, but people who have already decided that Fox and Newsmax are centrist and OANN is right-leaning are not going to evaluate things fairly anymore.
