The podcast Twenty Thousand Hertz is a show about the world's most interesting and recognizable sounds. I think of it as almost a sibling of 99% Invisible: lovingly produced and reported deep dives into everyday things that make you see the world differently. In case of Twenty Thousand Hertz , hear the world differently. We’ve collaborated a number of times, but we’re featuring them today because our sibling podcast produced an episode with my actual sibling Leigh Marz, co-author of the book Gol...
Mar 17, 2023•33 min•Transcript available on Metacast Back when whale oil was mainly used as a fuel to burn in lanterns and streetlights, an enterprising man named William F. Nye found a new way to sell whale oil to a rapidly changing world: as a lubricant for all the new fangled machines. Nye specialized in specialization- selling different oils for watches, sewing machines, bicycles. Lubrication has had a largely invisible role in the design of the modern world, but its importance cannot be overstated. A Whale-Oiled Machine Subscribe to SiriusXM ...
Mar 14, 2023•35 min•Transcript available on Metacast If we’ve learned anything from watching the turnover of tech giants like Yahoo! and MySpace, it’s that internet darlings rise and fall. And there’s something darkly fascinating about watching it happen in realtime. Maybe we’re seeing it now with Twitter and Facebook– some of us will mourn the loss of the communities and connections that we’ve created in the virtual spaces owned by these billion dollar companies... While others will enjoy visiting the graves of these once unstoppable behemoths to...
Mar 07, 2023•43 min•Transcript available on Metacast One study from 2018 found that Major League Baseball umpires blow about 14 calls every game. That’s 34,000 bad calls every year. And it makes a difference. A blown strike call can decide a win or a loss, a championship or six months at home, wondering what could have been. And while umpires are about 97% accurate in calling balls and strikes, Major League Baseball has been considering something drastic. Something to take us up to 100% accuracy. They have a plan to replace human umpires with robo...
Feb 28, 2023•28 min•Transcript available on Metacast In the 1980s a Polish anti-communist group called the Orange Alternative used cute images of a mythical creature with a tiny pointed hat to spread its anti-authoritarian message. That innocent symbol of an impish dwarf amplified a powerful political message to the world, which ultimately contributed to the fall of the Soviet Union. This approach is being used in creative and clever ways today by people protesting Russia's invasion of Ukraine. Orange Alternative Subscribe to SiriusXM Podcasts+ on...
Feb 22, 2023•32 min•Transcript available on Metacast When LA punks were looking for a place to play in the late 1970s, Chinatown welcomed the unruly scene. But it was an uneasy alliance that led to fierce rivalries, hurt feelings, blatant racism, and broken toilets. At the center of it all was a 62 year old Chinese immigrant named Esther Wong, aka Madame Wong, aka The Godmother of Punk.

Feb 14, 2023•43 min•Transcript available on Metacast On Aug. 1, 1942, the nation’s recording studios went silent. Musicians were fed up with the new technologies threatening their livelihoods, so they refused to record until they got their fair share. One Year 's Evan Chung explores one of the most consequential labor actions of the 20th century, and how it coincided with an underground revolution in music led by artists like Charlie Parker and Dizzy Gillespie.

Feb 08, 2023•51 min•Transcript available on Metacast In the 20th century, Iowa high school girls basketball was HUGE but it was not the game we know today. In 6-on-6 basketball, the three forwards only play offense. And the three guards only play defense. No one is allowed to leave their assigned half of the court. 6-on-6 still uses the full length of a basketball court, but in a different way than 5-on-5. In 6-player, three forwards from one team and three guards from the opposing team play at one end of the court. Meanwhile their teammates wait ...
Jan 31, 2023•42 min•Transcript available on Metacast If you live in South Africa, you definitely know someone who runs ultra-marathons, probably lots of someones. Here, ultras are the stuff of a whole country’s new years resolutions and mid-life crises. They’re the kind of thing that a totally ordinary, not-athletic person wakes up one day and decides they’re going to do -- and then does. In one of the most economically unequal countries in the world, extreme distance running is a sport that feels like it includes everybody. And improbably, that i...
Jan 24, 2023•42 min•Transcript available on Metacast Back in 2017 we ran an episode about the history of Brazil's iconic, yellow national soccer jersey. We were reminded of that story during the recent world cup, and then again on January 8th as a mob of right wing rioters attacked the Brazilian capital, many of them wearing those iconic yellow shirts. Needless to say the story of the yellow jersey has taken some real twists and turns in recent years, so today we’re going to rerun the original story about the jersey’s origins, and then producer Em...

Jan 10, 2023•34 min•Transcript available on Metacast This time of year, right in the middle of the holiday season, there's a beloved, frenzied tradition playing out in Filipino households all around the world, with which reporter Gabrielle Berbey is intimately familiar.

Dec 21, 2022•37 min•Transcript available on Metacast The whole conceit of this show is that if look at the world in the right way, you’ll see stories everywhere. Some of the stories are epic power struggles chronicling the construction of a famous skyscraper or the founding of a city; but other stories are more modest, smaller in scope and scale. We call those mini-stories and they're part of an ongoing, end-of-the-year tradition in which 99pi producers and friends of the show talk to host Roman Mars about something cool and fun that you can tell ...
Dec 14, 2022•37 min•Transcript available on Metacast If you’ve ever flipped through the radio dial — not satellite, not podcasts, but good old-fashioned AM and FM radio — you may have noticed something. Right wing radio talk is everywhere. But the airwaves weren't always so dominated by such a narrow range of voices. Reporter and friend of the show Katie Thornton has the story of how talk radio has evolved (and perhaps devolved at times) over the past century, and what all of it means for the airwaves today. The Divided Dial Hear the rest of the t...
Dec 06, 2022•46 min•Transcript available on Metacast Wildlife and urban development don’t usually go well together. Roads in particular fracture the habitats of wide-ranging animals. It restricts their movements and makes it harder for them to find food or a mate. But biologists and urban planners have started working together –- crafting a plan to try to help pumas move more safely around the city. And in the process this one cat, dubbed P-22, has turned into something of a celebrity—the symbol of a movement to redesign our cities and make the bu...
Nov 29, 2022•30 min•Transcript available on Metacast Los Angeles' El Peatonito is part of a subset of real life superheroes who are more focused on things like picking up trash and taking on civic issues than catching criminals in alleys. These super citizens take their inspiration from comic books but in some ways have more ambitious goals than defeating a make believe villain. They are out to solve big societal problems. Wherever a city is plagued by traffic accidents, or people are living on the streets…these heroes heed the call of service. Su...
Nov 22, 2022•27 min•Transcript available on Metacast When people ask me what my favorite episode of 99% Invisible is, I have a hard time answering. Not because they’re all my precious little babies or some such nonsense, but mostly it’s because I just can’t remember them all and there’s no simple criteria to judge them against each other. But the show is definitely in contention for the best episode we’ve ever made. It just has everything– engaging storytellers, brilliant reporting, and a compelling history of a moment when the world really change...

Nov 02, 2022•37 min•Transcript available on Metacast The basic mechanics of the bike are pretty simple --- it’s basically a triangle with wheels and a chain drive to propel it forward. No batteries or engines. It seems obvious in hindsight .... And that’s why most people guess the bike was invented a long time ago. Yet the ‘running machine,' a kind of early proto-bike, debuted around 1817.

Oct 18, 2022•47 min•Transcript available on Metacast The vuvuzela is a two foot long injection-molded plastic horn. It only plays one note: a B flat. And it gradually became a regular feature of South African soccer. But prior to the 2010 World Cup, the rest of the world had never heard anything quite like it. Even people in the soccer world didn’t know what they were. But by the time the first game of the tournament was underway, vuvuzelas were all over. For critics, the vuvuzela was a relatively new, mass produced noisemaker. But supporters ende...
Oct 11, 2022•32 min•Transcript available on Metacast Jamaica is famous around the world for its music, including genres like ska, dub, and reggae. It’s tempting to think that the powerful amplifiers and giant speakers at the dance parties were designed to perfectly capture Jamaica’s indigenous sounds. But it’s actually the other way around. Those speakers and amps came first. And the electricians, mechanics and engineers who built and adapted that technology would then play a decisive role in the creation of Jamaica’s modern music. They helped pio...

Sep 20, 2022•49 min•Transcript available on Metacast Adam Rogers has been thinking and writing about what’s known in the industry simply as "search." For the last decade, people have been grumbling about not being able to find things online, both in our private data and on the public web, despite ever-evolving algorithms. Ever since humans started writing stuff down, the struggle has been in how to organize it all so that its contents wouldn't be lost in the stacks. Search has always been an attempt to fix that problem. Search and Ye Might Find Su...
Sep 14, 2022•36 min•Transcript available on Metacast In downtown Windhoek, Namibia -- at the intersection of Fidel Castro Street and Robert Mugabe Avenue -- there's an imposing gold building with an affectionate nickname: the Coffee Maker. This notable structure was built to commemorate Namibia’s fight for independence from apartheid South Africa, which it achieved in 1990. And for many of the visitors, the museum feels like a huge achievement. But for a museum that commemorates throwing off the chains of colonialism and forging a new era of self-...
Sep 06, 2022•36 min•Transcript available on Metacast Back in March, Netflix picked up a long running Japanese TV program based on a children’s book from the 1970s. The show is called Old Enough , but the name of the original Japanese program translates to My First Errand . Because in each episode, a child runs an errand for the very first time. Episodes are only 10 to 20 minutes long, but in that short time a toddler treats the audience to a bite-sized hero's journey. My First Errand is a gimmicky show with hokey music and a laugh track, but it’s ...
