Siebert, Schramm, and Peterson outlined four theories of international mass communication, namely authoritarian, libertarian, social responsibility, and Soviet communist. These theories are still relevant today but are seen as ideal rather than exact models for twenty-first-century media. McLuhan, Carey, and Innis focused on communication technology and its impact on society, while Gramsci, Marx, and Habermas discussed media in the context of power relations and ideology. Eco, Barthes, and de Saussure were semioticians who analyzed the meaning and interpretation of signs and symbols.
