CSPAN’s think tank coverage is 51% right wing.

A new study by the Center for Economic and Policy Research “finds that right-wing think tanks got 51 percent of C-SPAN’s total coverage in 2006, while left-of-center think tanks only got 18 percent of their coverage (a mere 5 percent of which were ‘progressive’ think tanks). The other 31 percent of coverage went to centrist groups.” As TAPPED’s Kate Sheppard points out, this is at odds with C-SPAN’s stated aspiration of “a balanced presentation of points of view.”

The study incorrectly lists the Center for American Progress as “center-left” rather than “progressive.”
