Only Fox News has maintained its audience size, and this is because of the increasing number of Republicans who regularly get news there. Four-in-ten Republicans (40%) now say they regularly watch Fox News, up from 36% two years ago and just 18% a decade ago. Just 12% of Republicans regularly watch CNN, and just 6% regularly watch MSNBC.

As recently as 2002, Republicans were as likely to watch CNN (28%) as Fox News (25%). The share of Democrats who regularly watch CNN or Fox News has fallen from 2008…

Most of those who regularly watch O’Reilly (63%) and Hannity (65%) are 50 or older; 44% of the public is 50 or older. By contrast, the Daily Show and Colbert Report have the youngest audiences of any outlet included in the survey. Large majorities of those who say they regularly watch the Colbert Report (80%) and the Daily Show (74%) are younger than 50; 55% of public is 18 to 49.
