Say what you will, but an awful lot of people still get news from prime-time news broadcasts and prime-time cable news, as well as from newspapers. According to AdWeek, for the week of Dec. 4, 2017, average daily viewership for the 3 major broadcast networks’ “evening news” broadcasts was a little north of 25 million. PBS NewsHour adds another 1.1 million or so. For Fox News, MSNBC, and CNN the combined total was just over 5 million, though this is overstated a bit because it adds the viewers for various news programs (e.g., Hannity + Tucker Carlson on Fox News, Rachel Maddow + Lawrence O’Donnell on MSNBC) and so it undoubtedly double-counts some viewers who watch multiple cable news shows; Hannity usually has the top-rated cable news show with around 700,000 viewers, a small fraction of the broadcast networks.
Average daily circulation of some major newspapers: Wall Street Journal 2.4 million, New York Times 1.9 million, .USA Today 1.7 million, LA Times 650K, San Jose Mercury 500K, NY Daily News 500K, NY Post 500K, Washington Post 500K, Chicago Sun-Times 500K, Denver Post 400K, Chicago Tribune 400K, Dallas Morning News 400K. Total daily paid newspaper circulation is around 35 million—well below its 1980s peak of 65 million, to be sure, but that’s still an awful lot of people getting news from conventional newspapers. And remember, in many cases there are multiple readers per household.
I’m perfectly well aware that many people now get most or all of their news from internet sources whether through active searches, news feeds, or second-hand through Facebook, Twitter and the like. But the vast majority of that information is coming from conventional news sources like CNN, the New York Times, etc. There are certainly others—HuffingtonPost, Politico, Breitbart—but conventional broadcast news, cable news, and print media dominate the flow of news over the internet. And just as with conventional media, the volume of that information, and the numbers of people paying attention to it, is much diminished on the weekends. Which is why every politician in the country, including the most tech-savvy, will still tell you that if you want to bury bad news, the best time to release it is late on a Friday, because that’s when it will get the least attention.
