On Friday night, Fox News' Sean Hannity featured an hour-long documentary that examined the origins of the "Obama-Mania-Media's liberal bias."

In Behind the Bias: The History of Liberal Media, Hannity says the roots of this bias "remains the mystery" and then cites a New York Times journalist's 1933 report from Stalin's Soviet Union and left-wing dominance of American intellectual life since the mid-20th Century as early drivers.

"The media have been apologizing for America's enemies from the Cold War through the War on Terror," Hannity said.

The first segment of Behind the Bias, originally uploaded by Fox News on April 22, 2011, can be viewed below.
