America's Media Watchdog. The mission of the Media Research Center is to bring balance to the news media. Leaders of America's conservative movement have long believed that within the national news media a strident liberal bias existed that influenced the public's understanding of critical issues. On October 1, 1987, a group of young determined conservatives set out to not only prove — through sound scientific research — that liberal bias in the media does exist and undermines traditional American values, but also to neutralize its impact on the American political scene. What they launched that fall is the now acclaimed — Media Research Center (MRC).
