a large-scale study commissioned by Columbia Journalism Review found that consumers of legacy media read and watched and were exposed on social media to a large variety of stories and opinions, while Breitbart sat at the center of a closed media ecosystem. In other words, a slight majority of Americans inhabit a fairly healthy public sphere without realizing it. Equating this space with the Trumpian media universe is not merely factually wrong, it is also giving Trump exactly what he wants: the erasure of distinction between truth and lies.
