Certainly, I think it is borderline madness that entities such as facebook are being called out in the current "fake news" discussion, this is far from anything new and does not come from media centralization or the internet.
Previously the only way to get news was through these slow, controlled channels. And the people controlling these channels were responsible for the content being delivered, so if a slanderous lie was published they could be held accountable.
But with Facebook I can make up anything I want, frame it as fact, and get it seen by millions of people. Many of whom will believe it if it is convenient for them to believe it. And many of whom will never realise or accept that is a lie. And nothing bad happens to me for sharing these lies, I just make a bit of money from the ads.
This is a phenomenon that can only happen with the awesome communication enabled by the internet. And it's much worse than minor press bias.
