CNN might be biased but Fox genuinely just has people on spouting demonstrably incorrect lies and conspiracy theories on a daily basis.
Smaller, "independent" news sources tend to be started up and funded by dodgy "think tanks" and dark money from well-off people with vested political interests. It's incredibly difficult to tell which ones are actually reliable (not many) regardless of what agenda they pursue.
At least the "big" news sources (apart from Fox these days apparently) can't afford to just make up biased shite all the time because they have to retain some reputation as brokers of actual news. Start going too biased and pandering to the fringes of the far left or far right just loses you your reputation and the sensible middle ground majority who watch for actual news and make up the majority of the viewership.
You see in the US what would happen in the UK if capitalism got ramped up even further and the whole media started off from a relatively blank slate like you've had in the US. We're incredibly lucky to have some public service broadcasting in the BBC. You can tell by the way their reporting is hated by the far right and far left alike that the people working there make fact-based reporting their top priority and don't have an editorial process that's almost entirely driven by the extreme, rabid minorities at either end of the political spectrum who can't look at anything in the world without applying their preconceived political filters to it.
Whichever country it is though, it really is sick how the media is weaponised to varying extents to influence the public in their views and opinions. You have to work really fucking hard to just get access to cold, hard facts and make up your own mind.
