About NewsBusters.org
Welcome to NewsBusters, a project of the Media Research Center (MRC), the leader in documenting, exposing and neutralizing liberal media bias.
In August of 2005, with the assistance of Matthew Sheffield of Dialog New Media, the MRC launched the NewsBusters blog to provide immediate exposure of liberal media bias, insightful analysis, constructive criticism and timely corrections to news media reporting.
Taking advantage of the MRC's thorough and ongoing tracking of liberal media bias, including a wealth of documentation and an archive of broadcast and cable news recordings dating back to 1987, NewsBusters plays a leading role in blog media criticism as a clearinghouse for evidence of liberal media bias. It combines this formidable archive and its compilers inside the MRC with the contributions of already-established netizen watchdogs.
The Media Research Center's mission is to bring balance and responsibility to the news media. The MRC was founded on October 1, 1987 by L. Brent Bozell III, who set out to not only prove — through sound scientific research — that this bias exists, but also to neutralize its impact on the American political scene.
