In 1975, advertising executive Gary Dahl sat in a bar listening to friends complain about their pets: the feeding, the walks, the vet bills. His deadpan reply was that the perfect pet is a rock. It never dies, never disobeys, and never needs a bath. Most bar jokes end there. Dahl saw a product. He persuaded two colleagues, John Haggerty and George Coakley, to risk their savings, bought ordinary st...

In the spring of 1989, PepsiCo took ownership of 17 Soviet submarines, a cruiser, a frigate, and a destroyer, paid for with soft drink syrup. To explain how that happened, this episode first dismantles the textbook story of barter. Adam Smith wrote in 1776 that early economies ran on swapping goods until the double coincidence of wants forced the invention of money. Anthropologists such as David G...

Compound interest is the bedrock of modern wealth building, yet Roman law and common law once condemned it as the worst kind of usury. Its old name was anatocism: interest charged on the principal plus all the interest already accumulated. Simple interest on $1,000 at 5 percent is a steady $50 a year. Compounding earns $52.50 in the second year, a difference that looks trivial until the curve bend...

Every choice comes with a ghost: the best alternative you gave up to make it. That is opportunity cost, and this episode uses it to redraw how costs are counted. Explicit costs are the receipts, like the bill for fixing a broken printer. Implicit costs are the production time lost while it sat idle, or the salary a founder never draws. Sunk costs, such as $50,000 already poured into a failing rest...

Gerald Ratner built one of the largest jewelry empires in the world and destroyed it with a joke. Born in London in 1949, he took his real education from the shouting vendors of Petticoat Lane Market, joined the family jewelry business in 1966, and as CEO in the 1980s tore up the hushed, intimidating model of the traditional jeweler. Fluorescent orange posters and cut prices turned the shops into...

In October 2013, a man in his late twenties sat in the science fiction section of San Francisco's Glen Park library, running an illegal marketplace that generated an estimated $1.2 billion in sales. Ross Ulbricht was a former physics and materials science student steeped in Austrian economics who spent about six months coding Silk Road and launched it in early 2011 as an experiment in unrestrained...

In August 1971 the British government quietly asked the United States to move $3 billion in gold out of Fort Knox, the financial equivalent of pulling a fire alarm. Under the Bretton Woods system designed by 44 nations in 1944, every dollar could be redeemed for gold at $35 an ounce, a promise that looked safe when America held 574 million ounces. But Vietnam spending, domestic programs, and a hot...

The original emblem of the Knights Templar shows two knights sharing one horse, because they were too poor to afford a second. In 1119 a French knight named Hugh de Payens and a handful of companions, nine in all, offered King Baldwin II of Jerusalem a monastic military order to protect pilgrims on the bandit-ridden road from Jaffa. Given quarters on the Temple Mount, they lived on donations until...

After World War II, Coca-Cola held 60 percent of the cola market. By the early 1980s that share had fallen under 24 percent, and younger drinkers preferred the sweeter taste of Pepsi. CEO Roberto Goizueta, who took over in 1980, declared there were no sacred cows, and a secret effort called Project Kansas produced a sweeter formula that beat Pepsi in blind taste tests, even in the loyal Southeast....

Before they wrote a line of commercial browser code, Jim Clark and Marc Andreessen drafted a 20-page pitch for an online gaming network for the Nintendo 64. When that fell through, they turned to the web. In April 1994 they founded Mosaic Communications, soon renamed Netscape after a trademark clash with the University of Illinois, and rebuilt a browser from scratch under the code name Mozilla, sh...

At its peak, one piece of software consumed 61 percent of external internet traffic on university campus networks. Napster launched in June 1999, created by Shawn Fanning and Sean Parker and named after Fanning's high school nickname. File sharing already existed on IRC, Usenet, and Hotline, but those tools were clunky and technical. Napster did one thing, MP3s, behind a simple search bar, and sud...

The first known NFT sold for $4. In May 2014, artist Kevin McCoy and technologist Anil Dash registered a short pulsing video called Quantum on a blockchain during a live presentation in New York, calling the idea monetized graphics and hoping it would help digital artists get credit and payment. Seven years later the same concept produced a market with $17 billion in trading volume, a $69 million...

MySpace began in August 2003 as a pragmatic copy of Friendster, built in just 10 days by employees of an internet marketing company called eUniverse. Written in ColdFusion instead of Java, it could add features at a blistering pace, and a mailing list of 20 million subscribers solved the empty room problem overnight. Its real hook was freedom: users could edit their pages with raw HTML, and teenag...

In late 1967 the New York Stock Exchange had 1,365 members, and exactly one of them was a woman. Muriel Siebert, known as Mickey, was born in Cleveland, Ohio in September 1928 and left Western Reserve University without a degree to care for her ill father. She moved to New York, learned the market from the ground up as an analyst of aviation and aerospace stocks, and founded Muriel Siebert and Com...

A drop-proof phone case can make you more careless with your phone, and that small shift in behavior is the seed of one of the most debated ideas in economics. Moral hazard arises when someone takes on more risk because another party will bear the cost. This episode traces the term from 17th century insurance ledgers, where it meant outright fraud by a policyholder of bad character, to the 1960s,...

In May 1984 a CBS control room descended into panic as a man in a thrift store shirt drained Press Your Luck of more than $100,000 without breaking a rule. This episode tells the story of Michael Larson, born in 1949 in Lebanon, Ohio, an air conditioning repairman and ice cream truck driver who spent his days watching a wall of 12 televisions for ways to get rich. Recording the show on a VCR and s...

In 1987 an advertising executive named Bob Bernstein was handed a solid gold replica of a cardboard box. The reason says everything about the Happy Meal: its real value was never the food. This episode begins in Guatemala in the mid 1970s, where franchise operator Yolanda Fernández de Cofiño bundled a hamburger, small fries, and a small sundae into the Menu Ronald to spare parents the chaos of fee...

In the early 1960s a mathematician sat at Nevada blackjack tables in wraparound sunglasses and a fake beard, quietly proving that the house could be beaten. This episode follows Edward O. Thorp from a tinkering childhood, when he became a certified ham radio operator at 12, through a physics degree and a 1958 PhD in mathematics at UCLA. As a professor he taught himself Fortran to run blackjack sim...

In 53 BC, at a royal wedding feast in Armenia, an actor performing the Bacchae carried onto the stage the real severed head of Marcus Licinius Crassus, until recently the richest man in Rome. This episode traces how he got there. As a young noble he saw his father and brother destroyed in the purges of Gaius Marius, fled to Spain, raised a private force of about 2,500 men, and joined Sulla. At the...

In 1958 Bank of America mailed 60,000 active, unrequested credit cards to residents of Fresno, California. The gamble caused financial chaos and created the modern credit card. This episode starts earlier, with metal charge coins on key rings, the Charga-Plate of 1928, the airlines' Air Travel Card, and the Diners Club card of 1950, which still had to be paid in full each month. What blocked a uni...

In August 1929, brokers had lent investors more than $8.5 billion to buy stocks, a sum greater than all the physical currency circulating in the United States. This episode examines the machinery behind the Wall Street crash rather than just its timeline. Beneath the boom of the 1920s, farmers were drowning in surpluses, factory wages had stagnated, and warehouses were filling with unsold goods. Y...

Rich as Croesus is a phrase that has outlived its subject by more than two thousand years, yet the real king destroyed his own empire by misreading an oracle. This episode reconstructs the life of the last king of Lydia, born around 620 BC in what is now Turkey. He won the throne from his half-brother Pantaleon in a bitter succession fight, forced his own nephew out of Ephesus, and conquered the w...

Kickstarter turned ordinary fans into venture capitalists who want a fantasy novel or a board game instead of equity. Launched in April 2009 by Perry Chen, Yancey Strickler, and Charles Adler, the site rested on a simple psychological device, the assurance contract: a creator sets a goal and a deadline, and if pledges fall even a dollar short, nobody is charged. This episode explains how that all...

It began with a message from a source known only as John Doe: my life is in danger. Attached were 2.6 terabytes of data, 11.5 million documents from the Panamanian law firm Mossack Fonseca, some dating back to the 1970s. This episode follows how Bastian Obermayer of the Süddeutsche Zeitung brought in the International Consortium of Investigative Journalists, and how 107 media organizations in 80 c...

In the 1830s roughly one of every hundred dollars in the United States belonged to John Jacob Astor. This episode traces how a butcher's son born in Waldorf, Germany in 1763 became America's first multimillionaire. At 16 he left for London and his uncle's musical instrument business, where he absorbed the workings of global trade. On the voyage to Baltimore he spent weeks talking with a fur trader...
