99% Invisible
Roman Mars
Have you ever stopped to consider the invisible systems that shape your daily life? 99% Invisible is a captivating exploration of the architecture, design, and infrastructure we often take for granted. Hosted by Roman Mars and a team of inquisitive producers, the show pulls back the curtain on the built environment, revealing the hidden stories behind the objects and policies that govern our world. Whether it is investigating the murky, multimillion-dollar industry of predatory towing, deconstructing the complex electrical grids keeping our cities cool during heat waves, or analyzing why a simple urban trash can requires years of political maneuvering to design, this podcast finds the extraordinary in the ordinary. The show excels at connecting the dots between technical infrastructure and human behavior, proving that even the most mundane city services are often the result of fascinating, decades-long policy adventures. Beyond physical space, the show frequently engages in thoughtful deep dives into societal frameworks, such as the historical evolution of the U.S. Constitution and how legal mechanisms reflect our collective identity. By blending expert interviews with meticulous research, 99% Invisible transforms how you see the world around you. It is essential listening for anyone who has ever wondered how our cities actually work—or why they sometimes don’t. Prepare to have your perspective permanently shifted as you uncover the complex, layered, and often invisible design choices that define our reality.
