Moving images have become an increasingly common feature in a wide range of museums, which are frequently populated with screens and audio-visual projections. But when did films start to be displayed in museum galleries? And what are the issues at stake when showing moving images in exhibition spaces? With an innovative and strongly interdisciplinary theoretical framework, this book offers an extensive investigation of the use of audio-visuals in exhibition design. Highlighting the continuities and fractures between different periods, contexts and practices, Elisa Mandelli shows the deep influence of audio-visuals on the configuration of the exhibition space, as well as on the relationship between museums and their visitors.
