You say "media" as if it's a singular entity. It is not. It encompasses Fox News (which I don't watch but I gather is a cesspool), The London Review of Books, Vogue, Infowars, YouTube, etc. A set of _competing_ companies. Not all of them support or supported (the Iraq) war. Like so many others that refer to "the media" in the same way, I have to ask:
Are you sure you're not falling into the trap of "I didn't see it, so it doesn't exist"?
The "media" has a major problem. Its main driver is its entertainment value. News is more entertaining when sensationalised and heavily biased. I don't think there is a conspiracy or negligence causing this. Just simple economic drivers. It's the same thing we see with fast food. Yeah it's bad, but it's exactly what the market demands.
The issue (in the US) is how many people read those Pulitzer winning stories vs. watched Fox News and other sources that are driven by the Murdoch/Ailes/Koch agenda.
Sadly, a lot of people in the US watch Fox News and think it is the only truth. (Check out mediamatters.org for some agenda monitoring).
There are comfy media bubbles on both sides of the ideological spectrum and it is a serious problem. It is easy to criticize the other bubble while sitting comfortably in your own (please note I don't mean you personally, just a general person). One important step to popping those bubbles is to keep the stream of good journalism flowing. This means protecting the fourth estate from unwarranted attacks and trying to restore people's faith in the media and a basic shared reality.
However that is not the only issue causing these bubbles. People are segregating themselves, both socially and geographically along ideological lines. Print media is increasingly losing subscribers to generally less informative mediums such as tv. Technological advances, many brought about by my own field of software engineering, make it easier and easier for people to wall themselves off from ideas that make them uncomfortable. These are much more difficult problems to solve, and I certainly have no definitive answers for them.
So I start where I can, trying to encourage strangers on the internet (and in real life) to step out of their bubble and read the truly important journalism that still exists in our world. In the meantime, I hope someone much smarter than me can fix the divide in the US that causes these ideological bubbles. Because right now we are sitting on a powder keg, and the media isn't the cause... it's an effect.
I would they lost some for their support but also others for later portrayal that was inaccurate in both directions. The media in the last decade has clearly taken a political side and they don't seem to understand that. There were even stories this week of the media reporting on the media! When the press becomes the story it has failed.
