I'm reminded of the 'Information Bubble' section in Wait But Why's 'A Sick Giant's essay. Essentially, once upon a time the big media outlets had an incentive to reach a broad audience. The biggest megaphone had to appeal across the political spectrum. Then, cable news, the Internet, etc. balkanized journalism. Everyone could easily shift themselves into whatever bubble they wanted to pretend was reality.
