Which podcast explores design and architecture, hosted by Roman Mars?

99% Invisible is the podcast hosted by Roman Mars that explores design and architecture.

Mars launched the show in 2010 as a collaboration with San Francisco public-radio station KALW and the American Institute of Architects’ San Francisco chapter. Its title reflects the idea that much of the built world is noticed only subconsciously: street signs, city planning, everyday objects, and architectural details often shape life without attracting attention.

The program became part of the Radiotopia podcast network and expanded from short episodes into richly produced narrative documentaries. Common mix-ups include confusing it with Design Matters, which is Debbie Millman’s interview podcast, or assuming that 99% Invisible covers only buildings. Its stories also examine infrastructure, typography, products, maps, and public spaces.

Mars is both the creator and the recognizable voice of the show. In 2021, SiriusXM acquired 99% Invisible Inc., bringing the independent production into the company’s wider podcast portfolio.
