Actually, I think the news media are just returning to their default setting. It seems to me that for a brief, glorious period, news providers sought to be unbiased and objective in their reporting and presentation of the news. I'm sure they never succeeded totally (due to both personal and institutional biases). However, you'll never hit what you don't aim for. At least they seemed to be trying.
I can still remember the screams from members of my generation in the 60s (the granddaddies of the screams heard today) to abandon any pretense of objectivity because something was so terrible that it had to be fought "tooth and nail". "Up against the wall pigs!" was the byword of the day in the late 60s. Then Watergate came along, and generations of journalists have been taught to look upon that as the paradigmatic triumph and ultimate peak experience for journalists. Today, these two attitudes have combined to spawn a monstrosity that preens self-righteously in a cultural and political echo-chamber, and then wonders why the public no longer respects journalism and journalists in general.
Of course, John & Jill Q. Public still think highly of those who echo their own opinion of things. Unfortunately, we now live in completely different universes depending on political and cultural orientation with our own distinctive media resources. So it goes.
I sometimes wonder whether it would ever be possible to have a media "bell curve" where the vast majority of information resources fit in the middle and were generally respected by all. (Today we have two separate bell curves that mutually despise each other).
At my age I doubt I would live to see it even if anyone in the media had any interest in trying.
