Unfreedom of the Press is a 2018 book authored by conservative commentator and radio host Mark R. Levin. The book critiques the modern American media landscape, particularly mainstream media bias, arguing that the press has abandoned objectivity and integrity, leading to a self-imposed 'unfreedom' through bias, self-censorship, and the promotion of propaganda as news. Levin contends that this internal degeneration, rather than external government oppression, has eroded public trust in journalism. The work draws on historical perspectives of the free press while accusing contemporary outlets of ideological uniformity, particularly left-leaning bias, and failing to uphold First Amendment principles. It became a bestseller, reaching #1 on the New York Times list, but faced criticism for lacking original research and relying on polemical rhetoric.
