At first glance, it looks like Fox and Breitbart began to tank compared to the competition. But Corcoran says not to jump to conclusions. "I wouldn't put this decline down to the content of the sites themselves," the analyst told HuffPost. "In the case of Breitbart, their likes and comments actually increased between June 2015 and March 2016. In the case of Fox, those numbers include all local affiliates to the Fox network, so it's a broad coalition of sites, many of which may be seeing challenges in the way that their content is engaged with in the News Feed."
