It's no secret that cable news networks have partisan reputations. But new research shows the divide extends beyond which party a network appears to support. Over the past decade, these networks have increasingly focused on criticizing the opposing political party, a tactic researchers say is less about informing viewers and more about "selling anger." "These networks are more interested in talking about the opposing political party rather than their own candidates. This was not the case 15, 20 years ago," said Diego Garcia, the ... co-author of the working paper. The findings show that politics dominates cable news, accounting for about 60% of all named individuals mentioned"rising to over 75% during election years. But more revealing is who gets talked about: MSNBC spends more time discussing Republicans than Democrats, while Fox News focuses more heavily on Democrats. In 2024, Fox covered Democrats 60% of the time, with MSNBC showing the reverse. Garcia speculates that cable networks began to test different kinds of content when social media became widespread in the mid-2010s, and discovered that outrage boosts viewership. "I think Fox was the first one to figure this out, and they started pushing this negative rhetoric in their news," he said. "They're actually now the No. 1 cable news channel in the U.S. by far." Fox News now commands over 60% of the cable news audience"a dramatic jump from a more evenly split landscape a decade ago.
