http://people-press.org/reports/display.php3?ReportID=319 Pew Research Center is a pretty highly regarded organization..... the poll linked above is very enlightening regarding the impact of cable news on the knowledge level of the citizenry. "Since the late 1980s, the emergence of 24-hour cable news as a dominant news source and the explosive growth of the internet have led to major changes in the American public's news habits. But a new nationwide survey finds that the coaxial and digital revolutions and attendant changes in news audience behaviors have had little impact on how much Americans know about national and international affairs." and, from further in the text of the article: "By contrast, the regular audiences for many other sources scored no higher than the sample average. The audiences for morning news (34% high knowledge), local TV news (35%), Fox News Channel (35%), blogs (37%), and the network evening news (38%) were not significantly different from the norm for the whole sample (35%). The audiences for CNN, internet news sites such as Google and Yahoo, local newspapers, and TV news organization websites scored slightly higher (41%-44% high knowledge)." fair...balanced...and dumbed down. who'd a thunk it?
