This essay investigates architecture's shift from construction to media over the last 50 years. At stake is the questioning of architecture's dependence on its traditional cumulative mediums, such as physical matter since its inception, Euclidean geometry in the classical era, printed plans and scale models since the Renaissance, photographic and multimedia imagery since modernity, and 3D and data modeling in recent decades. If the 1970s and 1980s were defined by the transition to the post-medium era with the simultaneous emergence of digital tools, architecture museums, and biennials, the 2000s and 2010s have been marked by the rise of post-occupancy in the second digital turn.
