It doesn't matter which one. My mother mainlines BBC News which is state-owned, establishment-centrist, has no adverts or profits, but has the same effect of dialing up the viewer's fear of the outside world.

It's actually CNN, but they flip to local news often too to hear about all the car wrecks and local murders and robberies and other things to make them afraid.

Fox and CNN are both bad, but different flavors of bad.

I had a relative for which it was CNN. We even share the same political views, but watching that stuff or having it on in the background literally from 8 am until midnight is tiring.
