Noam Chomsky is an American linguist, philosopher, and activist known for his criticism of US foreign policy. He co-created theories on linguistics and developed the theory of Manufacturing Consent, which argues that mass media distorts news to suit business interests like profit and advertisers as well as the government. Chomsky identified five filters that shape media reporting: ownership and profit motives, reliance on advertising, sourcing of information, fear of negative responses, and use of fearmongering about threats.
