Episodes

  1. 284- Hero Props: Graphic Design in Film & Television

    When a new movie comes out, most of the praise goes to the director and the lead actors, but there are so many other people involved in a film, and a lot of them are designers. There are costume designers and set designers, but also graphic designers working behind the scenes on every single...

  2. 283- Dollhouses of St. Louis

    Back in the 1950s, St. Louis was segregated and The Ville was one of the only African-American neighborhoods in the city. The community was prosperous. Black-owned businesses thrived and the neighborhood was filled with the lovely, ornate brick homes the city has become famous for. But driving...

  3. 282- Oyster-tecture

    New York was built at the mouth of the Hudson River, and that fertile estuary environment was filled with all kinds of marine life. But one creature in particular shaped the landscape: the oyster. It is estimated that trillions of oysters once surrounded New York City, filtering bacteria and…

  4. 281- La Sagrada Familia

    The line to enter Barcelona’s most famous cathedral often stretches around the block. La Sagrada Família, designed by Antoni Gaudí, draws millions of visitors each year. There are a lot of Gothic churches in Spain, but this one is different. It doesn’t look like a Gothic cathedral. It looks...

  5. 280- Half Measures

    The United States is one of just a handful of countries that that isn’t officially metric. Instead, Americans measure things our own way, in units that are basically inscrutable to non-Americans, nearly all of whom have been brought up in an all-metric environment. Most of the world uses meters,...

  6. 279- The Containment Plan

    It’s hard to overstate the vastness of the Skid Row neighborhood in Los Angeles. It spans roughly 50 blocks, which is about a fifth of the entire downtown area of Los Angeles. It’s very clear when you’ve entered Skid Row. The sidewalks are mostly occupied by makeshift homes. A dizzying array of...

  7. 278- The Athletic Brassiere

    Among the most important advances in sports technology, few can compete with the invention of the sports bra. Following the passage of Title IX in 1972, women’s interest in athletics surged. But their breasts presented an obstacle. Bouncing breasts hurt, as women getting in on the jogging craze...

  8. 277- Ponte City Tower

    Ponte City Tower, the brutalist cylindrical high-rise that towers over Johannesburg, has gone from a symbol of white opulence to something far more complicated. It's gone through very hard times, but also it’s hopeful. It’s a microcosm of the South Africa’s history, but it’s also a place that…

  9. 276- The Finnish Experiment

    Around the world, there is a lot of buzz around the idea of universal basic income (also known as "unconditional basic income" or UBI). It can take different forms or vary in the details, but in essence: UBI is the idea a government would pay all citizens, employed or not, a flat monthly sum to...

  10. 275- Coal Hogs Work Safe

    Coal miner stickers started out as little advertisements that the manufacturers of mining equipment handed out. Even before the late 1960s, when mining safety laws started requiring reflective materials underground, miners used those stickers to stay visible to each other. As time passed, the...

  11. 274- The Age of the Algorithm

    Computer algorithms now shape our world in profound and mostly invisible ways. They predict if we’ll be valuable customers and whether we’re likely to repay a loan. They filter what we see on social media, sort through resumes, and evaluate job performance. They inform prison sentences and…

  12. 273- Notes on an Imagined Plaque

    Monuments don't just appear in the wake of someone's death -- they are erected for reasons specific to a time and place. In 1905, one such memorial was put up in downtown Memphis, Tennessee, to commemorate Nathan Bedford Forrest, who had died in 1877. This week, we feature the story of an…

  13. 272- Person in Lotus Position

    Tech analysts estimate that over six billion emojis are sent each day. Emojis, which started off as a collection of low-resolution pixelated images from Japan, have become a well-established and graphically sophisticated part of everyday global communication. But who decides what emojis are...

  14. 271- The Great Dismal Swamp

    On the border of Virginia and North Carolina stretches a great, dismal swamp. The Great Dismal Swamp, actually -- that's the name British colonists gave it centuries ago. The swamp covers about 190 square miles today, but at its peak, before parts of it were drained and developed, it was around…

  15. 270- The Stethoscope

    Imagine for a moment the year 1800. A doctor is meeting with a patient - most likely in the patient’s home. The patient is complaining about shortness of breath. A cough, a fever. The doctor might check the patient’s pulse or feel their belly, but unlike today, what’s happening inside of the...

  16. 269- Ways of Hearing

    When the tape started rolling in old analog recording studios, there was a feeling that musicians were about to capture a particular moment. On tape, there was no "undo." They could try again, if they had the time and money, but they couldn’t move backwards. What’s done is done, for better and...

  17. 268- El Gordo

    In Spain, they do the lottery differently. First of all, it's a country-wide obsession -- about 75% of Spaniards buy a ticket. There’s more than one lottery in Spain, but the one that Spaniards are the most passionate about is “La Lotería de Navidad” (“The Christmas Lottery”). This lottery has...

  18. 267- The Trials of Dan and Dave

    This is the story of an ad campaign produced for the 1992 Olympic games in Barcelona. Perennial runner-up in the sports shoe category, Reebok, was trying to make its mark and take down Nike. They chose two athletes, plucked them out of obscurity, gave them Reeboks to wear, and turned them into...

  19. 266- Repackaging the Pill

    Most people are familiar with at least one version of the birth control pill's packaging -- a round plastic disc which opens like a shell and looks like a makeup compact. But the pill wasn’t always packaged this way. The first birth control pill to hit the market came in a simple glass bottle of...

  20. 265- The Pool and the Stream

    This is the story about a curvy, kidney-shaped swimming pool born in Northern Europe that had a huge ripple effect on popular culture in Southern California and landscape architecture in Northern California. A documentary in three parts by Avery Trufelman.

  21. 264- Mexico 68

    The 1968 Olympics took place in Mexico City, Mexico. It was the first games ever hosted in a Latin American country. And for Mexico City, the event was an opportunity to show the world that they were a metropolis as worthy as London, Berlin, Rome or Tokyo to host this huge international affair....

  22. 263- You Should Do a Story

    "You should do a story..." is the first line to a lot of the conversations you have when you work at 99pi. This week we look into a bunch of those stories suggested by our listeners and present them to you: trademarks, desire paths, electric clocks, and a bevy of regional design solutions.

  23. 262- In the Same Ballpark

    In the 1992, the Baltimore Orioles opened their baseball season at a brand new stadium called Oriole Park at Camden Yards, right along the downtown harbor. The stadium was small and intimate, built with brick and iron trusses—a throwback to the classic ballparks from the early 20th century. It…

  24. 199- The Yin and Yang of Basketball

    In 1891, a physical education teacher in Springfield, Massachusetts invented the game we would come to know as basketball. In setting the height of the baskets, he inadvertently created a design problem that would not be resolved for decades to come. The Yin And Yang Of Basketball This piece is...

  25. 261- Squatters of the Lower East Side

    In 1987, three years after moving to New York City, Maggie Wrigley found herself on the edge of homelessness. She was trying to figure out where to stay, when she heard about an abandoned tenement building on the Lower East Side. It was owned by the city, but it had been left empty and...

  26. 260- New Jersey

    Soccer came to Brazil in the late 19th century. It was first a game of the elites but then over time became a game of the poor and working class. In this sense, says BBC journalist Fernando Duarte, soccer was the country’s true revolution. And if soccer is Brazil’s revolution, the Brazilian…

  27. 259- This Is Chance: Anchorwoman of the Great Alaska Earthquake

    This episode was recorded live as part of the Radiotopia West Coast Tour. It was the middle of the night on March 27, 1964. Earlier that evening, the second-biggest earthquake ever measured at the time had hit Anchorage, Alaska. 115 people died. Some houses had been turned completely upside down...

  28. 258- The Modern Necropolis

    In the town of Colma, California, the dead outnumber the living by a thousand to one. Located just ten miles south of San Francisco, Colma is filled with rolling green hills, manicured hedges, and 17 full size cemeteries (18 if you include the pet cemetery). 73% of Colma is taken up by…

  29. 257- Reversing the Grid

    For most people, electricity only flows one way (into the home), but there are exceptions -- people who use solar panels, for instance. In those cases, excess electricity created by the solar cells travels back out into the grid to be distributed elsewhere. And in some states, people can can be...

  30. 256- Sounds Natural

    In most wildlife films, the sounds you hear were not recorded while the cameras were rolling. Most filmmakers use long telephoto lenses to film animals, but there’s no sonic equivalent of a zoom lens. Good audio requires a microphone close to the source of the sound, which can be difficult and...

  31. 255- The Architect of Hollywood

    Los Angeles is rich with architectural diversity. On the same block, you could find a retro-futuristic Googie diner next to a Spanish-style mansion, sitting comfortably alongside a Dutch Colonial dwelling, all in close proximity to a Deconstructivist concert hall. In the golden era of Hollywood…

  32. 254- Containers

    We’re based in beautiful downtown Oakland, CA which is a port city in the San Francisco Bay. Massive container ships travel across the Pacific and end up here. From miles away you can see the enormous white cranes that pull giant, uniformly-sized metal boxes off the ships. People say the cranes…

    more
  33. 253- Manzanar

    When Warren Furutani was growing up in Los Angeles in the 1950s, he sometimes heard his parents refer to a place where they once spent time -- a place they called “camp.” To him “camp” meant summer camp or a YMCA camp, but this was something different. During World War II the US government...

  34. 252- The Falling of the Lenins

    On the night of December 8, 2013, a huge crowd gathered on a tree-lined boulevard in downtown Kiev, Ukraine. The crowd was there to watch as a statue in the boulevard was pulled down by a crane. The toppled statue was of Vladimir Lenin - the communist leader who started the revolution that…

  35. 251- Negative Space: Logo Design with Michael Bierut

    Logos used to be a thing people didn’t really give much thought to. But over the last decade, the volume and intensity of arguments about logos have increased substantially. A lot of this is just the internet being the internet. Logo redesigns, in particular, attract a lot of hyperbolic vitriol.…

  36. 250- State (Sanctuary, Part 2)

    In the 1980s, the United States experienced a refugee crisis. Thousands of Central Americans were fleeing civil wars in El Salvador and Guatemala, traveling north through Mexico, and crossing the border into the U.S. [Note: Just tuning in? Listen to the previous episode.] In response to this mass...

  37. 249- Church (Sanctuary, Part 1)

    In the 1980s, Rev. John Fife and his congregation at Southside Presbyterian Church began to help Central American migrants fleeing persecution from US backed dictatorships. Their efforts would mark the beginning of a new — and controversial — social movement based on the ancient religious concept...

  38. 248- Atom in the Garden of Eden

    As the world entered the Atomic Age, humankind faced a new fear that permeated just about every aspect of daily life: the threat of nuclear war. And while the violent applications of atomic research had already been proven, governments and scientists hoped this powerful technology held promise…

  39. 247- Usonia the Beautiful

    Frank Lloyd Wright believed that the buildings we live in shape the kinds of people we become. His aim was nothing short of rebuilding the entire culture of the United States, changing the nation through its architecture. Central to that plan was a philosophy and associated building system he...

  40. 246- Usonia 1

    Frank Lloyd Wright was a bombastic character that ultimately changed the field of architecture, and not just through his big, famous buildings. Before designing many of his most well-known works, Wright created a small and inexpensive yet beautiful house. This modest home would go on to shape the...

  41. 245- The Eponymist

    Eponym (noun): A person after whom a discovery, invention, place, etc., is named or thought to be named; a name or noun formed after a person. An eponym, almost by definition, has some kind of story behind it -- some reason it came to be named after a specific person. In this double-feature...

  42. 244- The Revolutionary Post

    Winifred Gallagher, author of How the Post Office Created America: A History, argues that the post office is not simply an inexpensive way to send a letter. The service was designed to unite a bunch of disparate towns and people under one flag, and in doing so, she believes the post office…

    On January 3, 1979, two officers from the Los Angeles Police Department went to the home of Eulia May Love, a 39-year-old African-American mother. The police were there because of a dispute over an unpaid gas bill. The officers approached her, and Love allegedly threatened them with a knife. They...

  47. 240- Plat of Zion

    The urban grid of Salt Lake City, Utah is designed to tell you exactly where you are in relation to Temple Square, one of the holiest sites for Mormons. Addresses can read like sets of coordinates. “300 South 2100 East,” for example, means three blocks south and 21 blocks east of Temple Square.…

  48. 239- Guano Mania

    In 2014, President Obama expanded the Pacific Remote Islands Marine National Monument, making it the largest marine preserve in the world at the time. The expansion closed 490,000 square miles of largely undisturbed ocean to commercial fishing and underwater mining. The preserve is nowhere near…

  49. 238- NBC Chimes

    The NBC chimes may be the most famous sound in broadcasting. Originating in the 1920s, the three key sequential notes are familiar to generations of radio listeners and television watchers. Many companies have tried to trademark sounds but only around 100 have ended up being accepted by the…

  50. 237- Dollar Store Town

    Dollar stores are not just a U.S. phenomenon. They can be found in Australia and the United Kingdom, the Middle East and Mexico. And a lot of the stuff—the generic cheap stuff for sale in these stores—comes from one place. A market in China, called the International Trade Market, or: the Futian...
