Eаrly cоmmunicаtiоns reseаrcher Paul Lazarsfeld pоsited a "Two-Step Flow" model of media effects. Explain this model and its implications prior to the era of the internet and social media. How might the "Two-Step Flow" model be relevant today in light of new media (Consider Druckman et al., 2018)? Hallin and Giles outline three basic media systems across Western democracies. What are the distinctive properties of the American media system as compared to others? And, how do these properties affect the programming that is delivered to the news audience? Explain the methodological tradeoffs between experiments and surveys in media effects research. Define and discuss three problems that scholars run into when they run laboratory experiments.
