I don’t think mediating information is a solution. That’s what started everything. “national enquirer sites ” are as old as the internet, but the real shift in power occurred just recently and it’s not new media’s fault. The rise of fake news is the result of the death of objective media, not the cause of it.
When you have by a wide margin most traditional news outlets campaigning for one candidate years before they even get nominated, you have a serious issue of professionalism. When those same “objective” news outlets turn the campaign into a reality show taht stars the “asshole achetype” in a lead role, you can not expect to be taken more seriously than the Daily Mail or Breitbart.
Once traditional media entered the buzzfeed game, they dropped their monopoly on credibility and truth became relative.
