Columbia Journalism Review
Columbia Journalism Review's mission is to encourage excellence in journalism in the service of a free society. Founded in 1961 under the auspices of Columbia University's Graduate School of Journalism, CJR monitors and supports the press as it works across all platforms, and also tracks the ongoing evolution of the media business. The magazine, offering a mix of reporting, analysis, and commentary, is published six times a year; CJR.org weighs in daily, hosting a conversation that is open to all who share a commitment to high journalistic standards in the US and around the world.
Our study of over 1.25 million stories published online between April 1, 2015 and Election Day shows that a right-wing media network anchored around Breitbart developed as a distinct and insulated media system, using social media as a backbone to transmit a hyper-partisan perspective to the world. This pro-Trump media sphere appears to have not only successfully set the agenda for the conservative media sphere, but also strongly influenced the broader media agenda, in particular coverage of Hillary Clinton.
