Media scholars are increasingly turning their attention to the study of infrastructure, bringing with them a multitude of methodological approaches. Their subjects and concerns cut across numerous subfields, questioning the communicative capabilities, environmental impact, and the very ontology of infrastructures that humans rely on. These concerns illustrate the urgent need to unite concerns of materiality with questions of form and poetics. Taking 'media and infrastructure' and 'media as infrastructure' together, this symposium brings together scholars from a range of disciplines to put considerations of infrastructural materiality in dialogue with aesthetics and form.
