Some of our favorite podcasts bring to light the stories behind the ordinary elements of life, and Roman Mars’ 99% Invisible is one of the best. What started as a radio project exploring architecture and urban design has expanded over the years to encompass the often-overlooked design of everyday things, from fashion trends to parking lots. Each episode uses that as a jumping-off point to unpack something larger—with fashion, the industry of trends and consumerism that rules our lives; with parking lots, how zoning codes impact the housing crisis. It’s a show that has consistently helped us feel smarter.
