The Center for Media and Democracy (CMD) is an American-based media research group founded in 1993 by environmentalist writer and political activist John Stauber. It publishes PR Watch, a quarterly newsletter edited by Laura A. Miller . Stauber and CMD research director Sheldon Rampton have published several books describing what they call the murky world of public relations. Another CMD project is the SourceWatch website (formerly called Disinfopedia), a Wiki, which CMD describes as "a collaborative project to produce a directory of public relations firms, think tanks, industry-funded organizations and industry-friendly experts that work to influence public opinion and public policy on behalf of corporations, governments and special interests."
CMD has stated that it is not affiliated with a political party, but that it does not pretend to lack opinions or a point of view.
