Between 2019 and 2023, media researchers from Södertörn University in UNISINOS and Universidade Federal de Santa Maria (UFSM) in Brazil, engaged in a collaborative effort to explore Scandinavian and South American perspectives on mediatisation, connecting universities from opposite sides of the world. The project aimed to promote a nuanced understanding of mediatisation theory from different cultural perspectives and media studies traditions, dismantle epistemological barriers, and provide new insights into societies undergoing the process of mediatisation. The chapters presented in this volume are grounded on the mobility of researchers across both countries where a productive knowledge exchange contributed to diversify epistemological, empirical, and methodological approaches to mediatisation theory, and provide new perspectives on mediatisation theory in contested media scenarios in Sweden, Brazil, and beyond.
