The ZIP code is less like a cold, clinical, ordered list of numbers, and more like a weird overgrown number garden. It started as a way to organize mail after WWII, but now it pops up all over our daily lives. You type it into the machine at the gas station to verify your credit card. You might type it into a rental search website if you're looking for a new apartment. Back in 2013, the ZIP Code contributed about 10 billion dollars a year to the US economy. On today's show, we turn our attention towards the humble ZIP code. Why was it born? How has it changed the mail? How has it changed the broader world? And... has it gone too far? This episode was hosted by Sally Helm. It was produced by Sam Yellowhorse Kesler with help from Willa Rubin. It was edited by Meg Cramer, and fact-checked by Sierra Juarez. It was engineered by Valentina Rodríguez Sánchez. Alex Goldmark is Planet Money's executive producer.

Ever since free trade opened up between the US and Mexico in the 1990s, trillions of dollars of goods have been going back and forth between the two countries, from cars to strawberries to MRI machines to underwear. But one major exception has been fresh American potatoes. Today on the show, we tell the trade saga of the American potato. For more than 25 years, there was a place that American potatoes could not go to freely. A place that the entire American potato industry was desperate to access. A vast, untapped market: Mexico. But standing in their way – the Mexican potato lobby and a trade loophole. This episode was hosted by Erika Beras and Jeff Guo. It was produced by Willa Rubin and edited by Meg Cramer. It was fact-checked by Sierra Juarez. Engineering by Cena Loffredo. Alex Goldmark is Planet Money's executive producer.

If you believe the hype, translators will all soon be out of work. Luis von Ahn, CEO and co-founder of the language learning app Duolingo, doesn't think AI is quite there... yet. In this interview, Greg Rosalsky talks with Luis about AI and how it's reshaping translation jobs and the language learning industry. We also ask him about headlines earlier this year suggesting Duolingo laid off some of its workers and replaced them with AI. This is one of Greg's Behind The Newsletter conversations where he shares his interviews with policy makers, business leaders, and economists who appear in The Planet Money Newsletter. This episode was first released as a bonus episode for Planet Money+ listeners earlier this year. We're sharing it today for all listeners.

Plus, a return to... returns.

This year, there was some economic good news to go around. Inflation generally ticked down. Unemployment more or less held around 4-percent. Heck, the Fed even cut interest rates three times. But for a lot of people, the overall economic vibes were more important. And the vibes... were still off. We might have achieved the soft landing the Fed was hoping for, but we saw some wackiness in the relationship between unemployment and job vacancies. Meanwhile, Bitcoin went to the moon. We have covered all of that in this past year, but which of these economic stories really defined the year? Fortunately, we don't have to decide. You all do. On today's show, a collaboration with our daily podcast The Indicator, we have Indicator Family Feud! Two Planet Money hosts enter, one Indicator host... also enters. And all three leave, having had a great time with lively discussion and light ribbing. Plus, some mild scheduling issues. But, we can't stress enough that no hosts were harmed in the making of this podcast. Then, we look ahead to 2025 to see what indicators we think will define the coming year – the future and the past, on our latest episode!
