99% Invisible · Pulse

99% Invisible is a narrative podcast about design, architecture, and the unnoticed details of the built world, hosted by Roman Mars and produced by SiriusXM (since the 2023 SiriusXM acquisition of the Stitcher network) with the long-running Radiotopia network association. Founded in 2010 as a public-radio collaboration between Roman Mars and KALW San Francisco plus the American Institute of Architects San Francisco chapter, the podcast has grown to approximately 600+ episodes through 2024 with weekly publication cadence and substantial cross-disciplinary editorial range covering urban design, product design, architectural history, infrastructure, social-design questions, the intersection of design with technology and culture.\n\nThe podcast's editorial-and-production approach — substantial archival research, professional sound design, the substantial Roman Mars narrator-voice production aesthetic, the substantial network of contributing reporter-producers (Avery Trufelman, Katie Mingle, Delaney Hall, Vivian Le, plus the broader Radiotopia network of producers) — has substantially influenced the broader narrative-podcast medium. The associated "The Power Broker" book club series (the substantial 2024 Robert Caro book-club running through 12 monthly episodes covering the 1,200+ page biography of Robert Moses) drove substantial audience engagement plus published book "The 99% Invisible City" (2020) by Roman Mars and Kurt Kohlstedt.\n\nThe target audience is design professionals, urbanists, architects, product designers, plus the broader design-curious general audience. The podcast operates within the broader Radiotopia network (the artist-owned Public Radio Exchange-affiliated podcast collective, since 2014) which includes Theory of Everything, Song Exploder, Reply All's former producers, and other narrative-and-creative podcast properties. The substantial post-2020 expansion of design-podcast-and-architecture-podcast medium has produced complementary podcasts but 99% Invisible remains the principal-prestige design-narrative podcast globally. Indian-listener engagement is substantial particularly among architecture-and-design students plus urban-planning professionals at major Indian design schools (NID Ahmedabad, IIAD New Delhi, NIFT, the substantial Indian architecture-school network).\n\nFor a globally-mobile professional with design-and-urbanism interests, 99% Invisible provides substantive intellectual content with reliable production quality. The podcast is freely available across major podcast platforms (Apple Podcasts, Spotify, Google Podcasts pre-2024-shutdown, the broader podcast-aggregator ecosystem). The substantial post-2020 SiriusXM acquisition and the broader podcast-platform consolidation has not substantially affected free-availability though some bonus content is paywalled.
