I hypothesize that this incentive to lock-in reader groups, has led to fragmentation of media and creating a lot of "info bubbles", or "interest based magazines". I think this is exacerbated by the dropping cost of information ( I have some thoughts on the process at http://dimitarsimeonov.com/2017/10/27/the-shifting-sweet-spo... )
I don't believe it is in Google's _strongest_ interest to provide truthful media, as Google doesn't make it's money from telling you truth.
I am optimist though.. and think in the future we'll have journalist's job be to aggregate a lot of that narrative and collect some micro-payments. And we'll have a lot fewer journalists, as there is less money in making these narratives.
