More on Media Matters

Media Matters for America is a 501(c)(3), web-based, not-for-profit organization. Media Matters was founded in 2004 by journalist and activist David Brock to "systematically monitor a cross section of print, broadcast, cable, radio, and Internet media outlets for conservative misinformation...every day, in real time." They publish research and analytic reports as well as rapid-response items and try to keep not only activists, but also the general public aware of misinformation. Some people consider Media Matters to be the media watchdog counterpart to the more conservative Media Research Center. They are also known for having declared a "War on Fox" in 2010.
