CRITICC is a research group in communication from a multidisciplinary perspective. Drawing on a critical approach to communication and media studies, we analyze the processes of communication ranging from interpersonal communication to hegemonic narratives in society, from a historical and structural approach. We address power relations as a cross-sectional phenomenon of communicative practices. The influence processes of interest groups are a good example of how communication is managed strategically to achieve and maintain power. The different research lines of CRITICC draw from this critical approach to examine diverse communicative phenomena.
