Prof. Anders Olof Larsson, Professor of Communication at Kristiania University College, shares his comparative social media research on party communication. We start out with a macro-level look at political parties' adoption of Facebook and Instagram across Europe, before focusing more specifically on Scandinavia. Prof. Larsson discusses the pros and cons of political merch contests in driving engagement, and how hashtag network structures have evolved over time on Facebook and Instagram in Norway. We also discuss post virality and Prof. Larsson's work comparing viral posts in Norway across Facebook, Twitter, Instagram, and YouTube. Here are the studies mentioned in the episode: Longitudinal studies of European party communication: Picture-perfect populism: Tracing the rise of European populist parties on Facebook (2022)The rise of Instagram as a tool for political communication: A longitudinal study of European political parties and their followers (2021)Studies using Norwegian data:‘Win a sweater with the PM’S face on it’ – A longitudinal study of Norwegian party Facebook engagement strategies (2020)‘Coherent clusters’ or ‘fuzzy zones’ – Understanding attention and structure in online political participation (2019)Winning and losing on social media: Comparing viral political posts across platforms (2019)
