This volume aims to deepen our understanding of the dynamic intersections of war and media in the rapidly transforming media ecology and the reordered geopolitical context. Since Russia’s fullscale invasion of Ukraine in February 2022, a new set of media practices and actors have entered the field of contemporary war. The volume examines the ways in which the digital media and communication environment is involved in and shape the war in Ukraine. The chapters in the volume analyse the expanding mesh of media—from mainstream broadcasting and press to social media platforms, and the latest digital technologies—and address four key themes: media infrastructures and the interplay between platforms, technologies, institutions and civic actors; open-source intelligence contributing to (dis)information about the war; the everyday life of war performed and documented on social media; and different interplays between the local and the global in the news coverage of the war.
