Twenty-First-Century Media Aesthetics looks at the connections between aesthetics and politics in a data-driven landscape. Since the last decade, foundational questions on politics and aesthetics have emerged in a world defined by technological infrastructures. The exceptional status of media as a uniquely human-focused infrastructure in the twentieth-century imagination now seems increasingly unsustainable as machine networks race beyond human perception. Populations, technologies, and logistics inhabit a sensory field, which has become a productive site for twenty-first-century political affect. This demands that we revisit older questions of social and cultural theory, and the metamorphoses of the political in the twenty-first century. Networked infrastructures have proliferated worldwide, where the majority of internet users today reside outside the West. Populations living in the global South now navigate confidently through the fluid spaces of network culture: marketing techniques are copied by influencers and internet celebrities, political actors repurpose media strategies, right-wing groups share memes and misinformation from Myanmar to Gaza, and scam factories operate globally, targeting users on every continent. This situation demands a transnational scholarly response. Twenty-First-Century Media Aesthetics brings together scholars of cinema, anthropology, law, contemporary art, and media theory from Asia, Europe, and North America. The chapters explore questions of forensics, publicity, archaeologies of cinema, mythopolitics, and the intermediations of the image in a networked landscape.
