Facebook Website Ecosystem [...]

But there’s also a new and distinctive sort of operation that has become hard to miss: political news and advocacy pages made specifically for Facebook, uniquely positioned and cleverly engineered to reach audiences exclusively in the context of the news feed. These are news sources that essentially do not exist outside of Facebook, and you’ve probably never heard of them. They have names like Occupy Democrats; The Angry Patriot; US Chronicle; Addicting Info; RightAlerts; Being Liberal; Opposing Views; Fed-Up Americans; American News; and hundreds more. Some of these pages have millions of followers; many have hundreds of thousands.

Using a tool called CrowdTangle, which tracks engagement for Facebook pages across the network, you can see which pages are most shared, liked and commented on, and which pages dominate the conversation around election topics. Using this data, I was able to speak to a wide array of the activists and entrepreneurs, advocates and opportunists, reporters and hobbyists who together make up 2016’s most disruptive, and least understood, force in media.Individually, these pages have meaningful audiences, but cumulatively, their audience is gigantic: tens of millions of people. On Facebook, they rival the reach of their better-funded counterparts in the political media, whether corporate giants like CNN or The New York Times, or openly ideological web operations like Breitbart or Mic. And unlike traditional media organizations, which have spent years trying to figure out how to lure readers out of the Facebook ecosystem and onto their sites, these new publishers are happy to live inside the world that Facebook has created. Their pages are accommodated but not actively courted by the company and are not a major part of its public messaging about media. But they are, perhaps, the purest expression of Facebook’s design and of the incentives coded into its algorithm — a system that has already reshaped the web and has now inherited, for better or for worse, a great deal of America’s political discourse.
