"FAIR, the national media watch group, has been offering well-documented criticism of media bias and censorship since 1986. We work to invigorate the First Amendment by advocating for greater diversity in the press and by scrutinizing media practices that marginalize public interest, minority and dissenting viewpoints. As an anti-censorship organization, we expose neglected news stories and defend working journalists when they are muzzled. As a progressive group, FAIR believes that structural reform is ultimately needed to break up the dominant media conglomerates, establish independent public broadcasting and promote strong non-profit sources of information."
