Agenda-Setting Dynamics in Media Communication

Agenda-setting dynamics explore how media organisations and information platforms influence the public’s perception of issue importance and emotional resonance. Originating from the notion that the frequency and prominence of topics in news outlets shape societal salience, contemporary research has extended the framework to encompass intermedia influence, emotional contagion and networked interactions. In a converged media environment, traditional broadcasters, social media platforms and public institutions operate in a reciprocal ecosystem: legacy news outlets may prime social networks, while trending topics online feed back into editorial agendas. Emotional framing and affective contagion further modulate these processes, as positive or negative sentiments diffuse across user communities and formal channels. Methodological advances—from vector autoregression and Granger causality to latent topic modelling and network analysis—have enabled fine-grained mapping of agenda flows during health crises, political campaigns and digital activism. Globally, such insights inform public-policy communication, crisis management and democratic discourse by revealing how governments, media gatekeepers and audiences co-construct issue salience and emotional tone.

Recent studies have integrated the emotional dimension into agenda-setting by analysing large-scale social media datasets from the early phase of the COVID-19 pandemic. Employing vector autoregression and Granger causality, researchers mapped affective agenda networks across public, government and media posts, revealing that government expressions of positive emotion significantly influenced media sentiment, which in turn shaped the public’s emotional responses. This work extends classic theory by demonstrating an affective feedback loop whereby official communications can steer both media tone and collective mood, underscoring mechanisms to maintain social cohesion and compliance during health emergencies.
