The big Sunday public affairs talk shows on network and cable TV are not in color, or even black and white, according to a new study.

Instead, said Media Matters, they are mostly just white -- as in the guests and hosts, who are also mostly male.

The liberal media watchdog, in its study of the six major shows through 2013, found that white men were the top gets for guests, led by Republicans Sen. John McCain, of Arizona, who appeared 21 times, Kentucky Sen. Rand Paul, 15 times, and Michigan Rep. Mike Rogers, chair of the Permanent Select Committee on Intelligence.

The white men guest breakdown: 60 percent on ABC's "This Week with George Stephanopoulos", 67 percent on CBS' "Face the Nation" with Bob Schieffer, 67 percent on "Fox News Sunday" with Chris Wallace, 62 percent on NBC's "Meet the Press" with David Gregory, and 54 percent on CNN's "State of the Union" with Candy Crowley. On MSNBC's "Up" with Steve Kornacki and Melissa Harris-Perry, white men represented a plurality of guests at 42 percent and 27 percent, respectively.

White men also nabbed the majority of solo interviews on the shows, said Media Matters.

The report, devoid of political commentary, helps to poke a hole in the view by many that the shows are liberal platforms and it also raises serious questions about gender and racial diversity in front of the camera on the shows.
