The media is not immune from criticism. Most media no longer has reporters, they have "story-tellers". We have "news personalities", who seek to offer "context" - which used to be known as bias. We have media owners who have a point of view - not unlike Horace Greeley or William Randolph Hearst. With the "yellow" journalists, it was a once-a-day delivery of slanted outrage. Now, we have a constant barrage - and I can't name a single source of unbiased journalism. EVERYBODY has a "point of view". Fox News is no more slanted toward the right than the New York Times - yes, the great "Grey Lady" - is biased to the left according to most media bias rankings.
To get the "real" picture, you have to take more than one source into account, and draw conclusions based on the facts you can glean from multiple sources. That takes work, and an educated populace willing to consider "inconvenient" truths. As we've seen here, some people are unwilling to do the work, or consider any point of view other than their own preconceived notions. What information they have is constantly reinforced by a barrage of blather from the same political point of view. The chamber echoes with multiple voices all saying the same thing - so it must be true.
So, what does radio do? It services a particular audience with a particular point of view in order to gather numbers it can sell to advertisers. If you can get the right 10% of the audience to listen, you're a media powerhouse. 90% of the audience or more may think you're spewing bilge (some listen just to "know the enemy"), but you'll be billing big and selling cemetery and rehab services. Most corporations feel far more responsibility to the stockholders than they do to the "public interest, convenience, and necessity".
Each generation believes less and less in "mainstream media". You've seen the videos. Young people not only don't know history, they don't care. They simply don't believe anything outside of their personal experience. They're a lot less interested in the "why" and "how" than they are promises of "free tuition" or "loan forgiveness."
As Pogo said (for those of you old enough to remember the old possum), "We have met the enemy, and they are us."
