"Digital Culture & Society" is a refereed, international journal, fostering discussion about the ways in which digital technologies, platforms and applications reconfigure daily lives and practices. It offers a forum for critical analysis and inquiries into digital media theory and provides a publication environment for interdisciplinary research approaches, contemporary theory developments and methodological innovation.The third issue "Politics of Big Data" edited by Mark Cot, Paolo Gerbaudo, and Jennifer Pybus, critically examines the political and economic dimensions of Big Data and thus details its contestation. The contributions focus on the materialities and processes which manifest Big Data and explore forms of value beyond the state and capital. These range from open data initiatives, social media metrics, machine learning algorithms, data visualisation to data dashboards, critical data analysis, and new modes of data action research and practice.
