Paper check usage is down 83% over 25 years

At the start of the millennium, more than 68 million checks were processed daily. Amid the adoption of automated clearinghouse (ACH) payment systems, that number has sunk to 12 million a day.

The long-lost art of coded postage stamps

In the 1800s, the postcard was a relatively new phenomenon, as was the post office. In the burgeoning system, recipients of mail had to sometimes pay prohibitively costly fees to receive it. So to get around the fees, a system of placing stamps on the envelopes in specific ways to communicate—a simple yes or no—was devised by clever mailers and expanded and codified by postcard companies into guides. Learn about the fascinating system here.

When modeling the fastest way to board passengers onto an airplane, research shows that random boarding is often faster than boarding in groups.

Customers wrote just one check a year in 2024, on average

Major retailers like Target have stopped accepting checks in recent years as real-time payment systems are increasingly being implemented across the US. This shift is considered an improvement in safety—as checks are vulnerable to fraud—but can lead to some exclusion for those without access to digital devices.

Anticipating moon tourism by 2000, Pan Am issued 'First Moon Flights' club cards

More than 93,000 cards were issued between 1968 and 1971, creating a waitlist that began when Gerhard Pistor, an Austrian journalist, visited a Viennese travel agency to request a flight to the moon. The cards were issued at no cost and numbered in the order they were issued.

American Express is credited with inventing the traveler's check

In the 1890s, then American Express President James C. Fargo was frustrated that he couldn't get cash while traveling in Europe outside of major cities. Marcellus Berry, an American Express employee, came up with the idea of a traveler's "cheque": a prepaid check, similar to cash, that requires the signature of both the customer and the receiving institution to be valid. American Express never modernized the spelling of the word "cheque" and stopped providing them at the end of 2020.

Why millions of telegrams are still sent every year

Telegrams enabled much faster communication across distances when they were invented in the 1800s, but they became generally obsolete after emails and cell phones were widely adopted. So why are 17 million still sent every year? A combination of factors: the legal requirement to send paper documents far and fast, the resistance to updating processes, and nostalgia.

Where did artful screen savers go? A history

Early on in the personal computer days, users and engineers realized screens could be damaged if the same image—of a button, a logo, or a navigation bar—stays static for too long. To preserve the screen, developers deployed screen savers—automatic reductions in the light intensity, or regularly changing patterns on the screen. These artful screen savers had a heyday in the 1990s, but have since lost popularity to the simple black screen. Read the history here.

Commercial air travel's early days: Flights were short, cold, depressurized, and generally comfortable

After World War II, airlines competed for their high-end passengers by offering cocktails, meals, and plush seats, cultivating the image of the elite "Jet Set." By the 1960s, air transport was completely changing global trade and offering big profits to companies able to ship via plane.

Why there are microchips in credit cards

Credit cards have evolved significantly since their invention in 1950, but security lagged in the US for years. Despite handling only a quarter of global transactions, the US once accounted for half of all credit card fraud. The 2013 Target data breach helped push the adoption of chip cards, reducing fraud but shifting risks to online scams.

A 2022 Gallup survey found that Americans are reading fewer books than ever before. An additional study found that the time people spend reading has dropped over the last 20 years. The most compelling narrative for the shift? Screens have stolen potential readers, occupying the time that they otherwise would’ve spent with books.

Many airports have dedicated stores for luggage, despite most passengers having luggage with them already

This podcast episode argues that airport luggage stores exist due, in part, to the security measures implemented after 9/11, creating capitve audiences of travelers. Some argue that airport luggage store shoppers coming from places where luggage is more expensive could be purchasing luggage in international airports. Specifically, the episode traces airport history from the very beginning to today's luggage store in your local Terminal B.

The US developed a coin circulation problem in 2020

As people reduced the frequency with which they paid for things in cash and change during the COVID-19 pandemic, opting for tap-to-pay systems or online shopping instead, the number of coins in circulation decreased.

Earlier this year, Gwendolyn Bruhn, who worked for Hawaiian Airlines in the 1940s, spotted herself in a photo blown up on an airport wall. Here's her story.

Thomas and Anne Rogers were famous counterfeiters in 17th-century England

The pair used a practice called “coin clipping,” shaving the edges off silver coins to decrease their weight before sending them back into circulation. When banknotes rather than coins gained popularity, counterfeiting methods evolved—in the 1700s, an early banknote counterfeiter named Mary Butterworth created counterfeit paper money using starched cloth and a hot iron to transfer the pattern of a banknote onto paper.
