The sociology of media and communications was never explicitly defined – nor was there ever an explicit debate about the sub-field. Not having a clear anchor makes it hard to define what its critical component should be. Nonetheless, a rich yet disconnected tradition of sociology and critical political economy allows flexibility to reconsider communication and social relations in the broader societal dynamics of capitalism. Specifying a critical sociological approach to communication can help better define the role of communication at the micro, mezzo and macro levels of society. The multi-paradigmatic heritage of sociological theory can provide new ways of criticising communication power in contemporary society. Diverse contemporary developments in the critique of political economy give a breadth of understanding of the capitalist mode of production and its internal dynamics. Sociology can add depth to understanding social relations within and beyond the production, distribution and consumption process. This introduction sets out the framework for the special issue.
