Media Matters for America

Media Matters for America (MMfA) is a non-profit left-leaning watchdog journalism organization. It was founded in 2004 by journalist and political activist David Brock as a counterweight to the conservative Media Research Center. It seeks to spotlight "conservative misinformation" in the U.S. media; its methods include issuing reports and quick responses. Two example initiatives include the "Drop Fox" campaign (2011–2013) that sought to discredit Fox News' "fair and balanced" claims; and a 2023 report about X (formerly Twitter) that highlighted antisemitism on the platform.
