Fox’s minimal influence is easily explained. While it’s the most popular cable news network, it still draws only a niche audience. Socolow provides the numbers: On an average night, about 2.4 million prime-time viewers tune in, which is about 0.7 percent of the total U.S. population. “With numbers like these,” Socolow writes, “it’s no surprise that Fox News often chases its viewers rather than leading them. In other words: It’s more likely that Fox News caters to the preexisting partisanship of its small but loyal audience than that Fox News actually changes anybody’s mind.”
