Long form content, unrestricted by executives telling people how to run their show, all that makes a big difference. There is no need for corporate bureaucrats to try to run things.
I'm don't want to be completely pollyannish about the past - there were probably things we weren't hearing about from those fewer outlets. But I'm also not sure how we move forward as a society in a situation where there are so many different shattered views of what is true.
We are “divided” now because we are basically in a battle for what is consensus reality, and the only way to have a satisfying answer to that question is to have unfettered access to the underlying facts and knowledge of who is who.
I'm concerned we're going to get to the point where people are willing to kill each other over what they consider to be their view of "consensus reality". That's happened often at other points in history. In many cases it was due to religious differences over what constituted "reality". I'm not so sure that many of these current squabbles over what constitutes "consensus reality" aren't religious in nature. Social media already seems to be pushing the limits of human nature in some destructive directions such that politics now is like holy war.
I think we need to focus more on the "consensus" part (including peacemaking and bridge building) instead of the "battle" part. I'm not seeing a lot of that happening. That requires a lot of humility as in we're all like blind people groping our way to figure out reality and none of us has the complete picture. Until we're ready to take on that kind of humility on a societal level, I think this "battle" you refer to can be a very dangerous endeavor.
