The Media Research Center is a politically conservative content analysis organization based in Reston, Virginia, founded in 1987 by activist L. Brent Bozell III. Its stated mission is to "prove—through sound scientific research—that liberal bias in the media does exist and undermines traditional American values" and to neutralize what they perceive as liberal bias in mainstream media.
