Monopoly

Did you know that Monopoly played a key role in the European theater of World War II? Originally conceived in 1903 by Elizabeth Magie Phillips as The Landlord's Game to highlight the inequities of capitalism, the board game was later rebranded by Parker Brothers in 1934.

When thousands of Allied soldiers, including Americans, were captured by German forces during WWII, the British Secret Service began manufacturing specialized editions to be smuggled into prisoner camps inside Red Cross packages. The German guards welcomed the games as harmless ways for prisoners to pass the time. Little did they know, these boxes contained customized silk maps, real local currency, and precise escape routes hidden within the board and game pieces. Intelligence experts estimate that up to 10,000 Allied soldiers successfully escaped enemy capture because of these rigged board games.

Silly String

In the early 1970s, inventors Leonard A. Fish and Robert P. Cox were working on an aerosol spray-on cast for broken limbs. Although they failed spectacularly, they patented the sticky mess as "foamable resinous composition." Eventually, American toy company Wham-O picked it up and re-labeled it as Silly String.

Decades later, this joke device went to war. In 2006, while stationed in Iraq, Specialist Todd Shriver and his unit found themselves lacking official gear to safely detect the invisible tripwires used to detonate explosives. Because the spray of Silly String could shoot more than 10 feet away and was very light, it became an unlikely but useful tactical tool.

Slinky

In 1943, naval engineer Richard James was attempting to design a spring system for naval battleships. When he accidentally knocked one of his prototypes off a shelf, he watched in fascination as it walked down a stack of books, onto his desk, and onto the floor. The Navy never bought his invention, but the world got the Slinky, selling over 100 million units in its first two years alone.

Years later, the toy’s military purpose came into fruition during the Vietnam War. U.S. communications troops operating in dense jungles frequently struggled with terrible radio reception. They quickly discovered that a standard steel Slinky could be stretched out and tossed over high tree branches to serve as an effective improvised antenna.

View-master

When the View-Master made its grand debut at the 1939 New York World’s Fair, it was marketed as an alternative to scenic postcards. Co-inventors Wilhelm Gruber and Harold Graves paired standard stereoscopes with circular cardboard reels containing seven 3D color film images, which allowed people to marvel at the Grand Canyon from the comfort of their homes.

By 1942, the United States military realized that this photographic novelty could become a useful tool. In the midst of WWII, the U.S. Armed Forces purchased more than 100,000 View-Master viewers and commissioned thousands of custom-made reels. Instead of tourist images, these reels featured detailed, three-dimensional models of enemy aircraft, naval vessels, and artillery. It allowed troops to practice identification, making it a critical asset for gunners and pilots.

Silly Putty

Silly Putty is another marvel of accidental wartime engineering. During WWII, the United States faced shortages of natural rubber due to several blockades. In an attempt to create a cheaper alternative, General Electric engineer James Wright mixed silicone oil with boric acid. The result didn’t work for tires, but it became a hit when packaged inside plastic eggs.

Eventually, this gooey and bouncy material caught the attention of NASA. In 1968, the crew of Apollo 8 packed Silly Putty into their spacecraft. In the zero-gravity environment, the astronauts used the sticky compound to secure their gear to the walls to prevent it from floating away around the cabin.

Buzz Lightyear

While Buzz Lightyear began his life as a fictional space ranger in Pixar’s 1995 hit Toy Story, the physical action figure manufactured by Thinkway Toys achieved a few real-world milestones that would make Andy proud.

In 2008, NASA launched an authentic Buzz Lightyear action figure into space aboard the Space Shuttle Discovery. Buzz spent a staggering 15 months living aboard the International Space Station. There, he worked alongside astronauts to film educational videos designed to teach school children across America about weightlessness, orbital mechanics, and microgravity physics.

LEGO

The famous toy company was founded by Danish carpenter Ole Kirk Christiansen in 1949. While LEGO first reached the US in the early 1960s, the plastic interlocking bricks didn’t become massively popular until the 1970s. Once American children adopted the new toy, it completely reshaped modern STEM education.

Although schools had experimented with bricks for decades, LEGO allowed teachers to develop structured curricula designed to teach kindergarteners fine motor skills and spatial mathematics. By the time those students reached high school, LEGO’s advanced kits were serving as the backbone for introductory robotics, engineering, and programming courses nationwide.

Mr. Potato Head

Created by American inventor George Lerner in 1951 and distributed by Hasbro, the original Mr. Potato Head didn’t include a plastic body, just sharp metal pins attached to plastic facial features. Despite the risk of children stabbing themselves, the toy made history as the very first toy ever advertised on television.

From there, Mr. Potato Head had a surprising career as a public servant. In 1985, he received four legitimate votes during the mayoral election in Boise, Idaho. In 1987, he officially dropped his plastic pipe to become the face of the American Cancer Society's "Great American Smokeout" anti-smoking campaign. He later joined forces with the League of Women Voters to boost voter turnout and today acts as an official travel ambassador for the state of Rhode Island.

Cabbage Patch Kids

When American businessman Xavier Roberts first created his "Little People" in 1978, nobody could have predicted that they would spark Black Friday riots by 1983. But beyond the hysteria, Cabbage Patch Kids went on to become national ambassadors.

In 1992 and 1996, the United States Olympic Committee selected the dolls as the first-ever official mascot of the US Olympic Team, traveling with the athletes to Barcelona and Atlanta. In 1999, the U.S. Postal Service immortalized them on a stamp celebrating the icons of 1980s American culture. Over the years, the franchise has collaborated with NASA on science education and raised thousands of dollars for disaster relief efforts.

Teddy Bear

Did you know Teddy Bears were born in the United States? In 1902, a Russian-born businessman and inventor named Morris Michtom was inspired by a cartoon published in The Washington Post to create what would become the most beloved toy in America. The cartoon depicted President Theodore Roosevelt showing compassion for a bear on a hunting trip in Mississippi.

Morris Michtom made a small plush bear cub, sent it to Roosevelt, and asked for permission to use his nickname, Teddy. After the president’s blessing, Mitchom placed the doll in the window of his Brooklyn store with the caption "Teddy’s bear." The success was so great that he began mass- producing them, and within a few years, he founded the Ideal Novelty and Toy Company, which would become the largest doll-making firm in the United States.

Blockbuster

During the 1980s and 1990s, Friday night often meant one thing for American families: a trip to Blockbuster. Browsing the aisles for a movie, debating what to watch, and grabbing popcorn at the counter became a weekly routine. But nothing lasts forever.

Born in 1985, Blockbuster conquered the massive home-video market with thousands of stores by the late 1990s and early 2000s, catering to families with at-home VCRs. Then technology changed everything. First came DVD-by-mail services like Netflix, followed by streaming, which left Blockbuster struggling. Late fees and inconvenience only pushed more customers away. The company filed for bankruptcy in 2010. Today, just one official store remains in Bend, Oregon, where visitors still stop by for a dose of the video-store era.

2

Kodak

Back in the day, almost every vacation, birthday, wedding, or holiday gathering seemed to include a Kodak camera, or at least a roll of Kodak film. Founded in 1881, Kodak helped keep the moments that filled family photo albums for generations.

From the 1960s through the 1990s, Kodak dominated the world of film and photography. But that success also made the company slow to accept that technology was changing. Ironically, Kodak helped invent one of the first digital cameras in 1975, yet it hesitated to embrace the future. By the 1990s and 2000s, digital cameras (and later camera phones) quickly replaced traditional film. In 2012, the company declared bankruptcy.

Pan Am

Long before flying became an everyday experience, Pan American World Airways, better known as Pan Am, was already carrying Americans across the world. It was founded in 1927, and during the 1960s and 1970s, the airline became a symbol of glamorous air travel.

Its famous blue globe logo was instantly recognizable, even to those who rarely flew. But by the late 1970s, rising competition, fuel costs, and financial troubles began weakening the company. After years of mounting losses and debt, Pan Am shut down in 1991. Even so, its fame was such that even today, more than 30 years later, we still remember it.

4

Woolworth’s

Before Woolworth's made the "five-and-dime" famous, shopping in America looked very different. For decades, Americans visited Woolworth’s for everything from toys and school supplies to household goods and everyday essentials. By the 1960s, the brand had become a familiar part of American life.

Created in 1879 by Frank Winfield Woolworth, the chain grew into one of the country’s largest retailers. But in the 1970s, malls and discount giants like Walmart changed the way Americans shopped, and Woolworth struggled to keep up. By the 1980s, the iconic chain was slowly disappearing. Most stores closed during the 1990s, and the Woolworth retail chain officially ended in 1997.

5

Circuit City

Testing giant stereo systems, browsing rows of CDs and video games, and shopping for the newest TV were all part of the experience at Circuit City, once one of America’s biggest electronics chains.

Founded in 1949 by Samuel S. Wurtzel in Richmond, Virginia, as "Wards Company," the retailer adopted the Circuit City name in 1984. During the 1980s, 1990s, and early 2000s, it became the go-to place for Americans buying a TV, stereo, computer, or any electronic device. But like many companies on this list, Circuit City struggled as shopping habits changed and online stores became more convenient. A controversial 2007 decision to lay off thousands of experienced employees further hurt the company’s reputation. Circuit City couldn’t survive mounting losses and closed all remaining stores in 2009.

6

Borders

Remember Borders? Born in 1971, its huge stores, filled with books, music, magazines, and cozy reading spaces, invited customers to spend entire afternoons there.

During the 1990s and early 2000s, the rise of large shopping malls actually helped Borders thrive, turning its bookstores into popular destinations inside malls across the US. But eventually, the company ran into a challenge it couldn’t overcome: online shopping and digital reading. Competitors like Amazon surged ahead, while Borders struggled to adapt and made costly business decisions, including outsourcing its online sales to Amazon for years. The company collapsed financially in 2011 and soon closed all remaining stores.

7

Bugle Boy

In the late 1980s and early 1990s, teenage fashion became almost synonymous with Bugle Boy. Famous across the country for its casual jeans and memorable TV commercials, the brand became a major part of American mall culture and was sold in department stores nationwide.

But fashion never stands still, and brands have to constantly adapt to survive. By the late 1990s, newer youth-oriented labels had taken over with fresh styles that quickly made Bugle Boy seem outdated. Sales began to fall, and after years of struggling to keep up with changing trends, the company closed its stores in 2001.

8

Howard Johnson’s restaurants

During the 1960s and 1970s, a stop at Howard Johnson's was part of the classic American road-trip experience for many families, and that was no accident.

Founded in 1925 in Quincy, Massachusetts, the famous orange-roofed chain reached its peak when America’s expanding highways and booming car culture made roadside travel more popular than ever. But by the late 1970s and early 1980s, the growing popularity of fast-food chains like McDonald's began changing the way Americans ate on the road. Drivers increasingly wanted meals that were faster, cheaper, and more standardized, while interstate highways also redirected traffic away from many older roadside locations. Unlike some other brands on this list, Howard Johnson’s faded away slowly over the decades. The last restaurant finally closed in 2022.

9

Burger Chef

In 1958, a name emerged as one of the pioneers of America’s growing fast-food industry: Burger Chef. By the late 1960s, the chain had more than 1,000 locations across the country and had become one of McDonald's’s biggest competitors.

Long before Happy Meals became famous, Burger Chef helped popularize the idea of marketing meals directly to children with toys and themed publicity. But during the fast-food wars of the 1970s, competition became fiercer than ever. While McDonald’s and Burger King expanded by leaps and bounds, Burger Chef struggled with financial problems and changing consumer tastes. In 1982, the company was sold to Hardee's, which gradually converted most Burger Chef locations into Hardee’s restaurants.

10

Sports Authority

Throughout the 1990s and 2000s, many Americans looking for running shoes, gym shorts, and sports gear headed straight to Sports Authority.

Known for its huge stores packed with athletic apparel, exercise equipment, bicycles, camping gear, and team sports products, Sports Authority became the ideal shopping destination for families and athletes across the US. But as online shopping rapidly changed retail in the 2000s, the company struggled to adapt. Heavy debt from expansion efforts and a slow shift to e-commerce eventually caught up with the chain. Sports Authority declared bankruptcy in 2016 and closed all remaining stores later that year.

What are bills made of?

Unlike other currencies, dollar bills are not made of paper or plastic. U.S. dollar bills are made from a special fabric blend composed of 75% cotton and 25% linen. This mix makes the bills extremely durable and resistant, and they can be folded about 4000 times before tearing.

2

What bills are valid?

Any U.S. dollar bill that was legally printed is valid, no matter how old, as American currency does not have an expiration date. While some bills might not be accepted by businesses of foreign exchange services due to their condition or if they are a discontinued version of the bill, the bills themselves are still valid, and American banks will accept them, though they might take them out of circulation.

3

American leaders

Five bills have a depiction of an American president. The exceptions are the $10 bill, with Alexander Hamilton on the front, and the $100 bill, with Benjamin Franklin. The $1 bill, depicting George Washington, is extremely symbolic: several elements are repeated 13 times as a nod to the thirteen colonies, and it showcases the Bald Eagle and the Eye of Providence as a sign of God watching over America.

4

A change in size

Did you know that dollar bills used to be so big that they were nicknamed "horse blankets"? Original dollar bills were 7.4 × 3.1 inches. In 1929, the Treasury Department reduced the size of bills to 6.14 × 2.61 inches to reduce production costs and materials. Old bills, though still valid, are worth much more as collector items.

5

Uniformity

Besides their value and design, all dollar bills have the same size (6.14 × 2.61 inches), color, and weight (1 gram) , which sets American currency apart from other countries where bills of different values are differentiated by size, color, or both. Why doesn’t the U.S. implement differences among bills? The cost of adapting vending machines, bank drawers, and ATMs to new bill sizes would cost billions of dollars.

6

Hard to copy

Originally, dollars were not green, but black. As time passed, green ink was favored, as it was cheap and did not fade as much as black. The new color also prevented people from using black-and-white cameras to create counterfeit money. Currently, dollar bills are predominantly green, but newer versions also include extra colors, such as pink, orange, or purple.

7

A $100,000 bill?

Have you ever seen a $500 or 1,000 dollar bill? What about a $100,000? Up until 1945, the U.S. Treasury printed $500, $1,000, $5,000, $10,000, and $100,000 notes , in addition to the values currently in use. These higher-value notes were mainly intended for bank and government use, but were sought by criminals as they made it easier to hide large amounts of money. Even though they were officially discontinued in 1969, these notes are still valid, though rare, and they have a high worth as collector's items.

8

No numbers

Unlike bills, American coins have different sizes and colors related to their value. Originally, gold, silver, and copper were used for coins, but modern coins are made of copper, zinc, or nickel. Besides their size and design, the value of each coin is printed in letters, not in numbers , alongside depictions of American presidents.

9

Liberty for all (the coins)

By law, all American coins must include six specific details : the word ‘Liberty’, the name of our country, the national motto "In God We Trust", the oldest American motto "E Pluribus Unum", the value of the coin, and the year. Each coin also includes a mint mark that shows where it was made: "P" for Philadelphia, "D" for Denver, "S" for San Francisco, and "W" for West Point.

10

A global currency

The American dollar is one of the most powerful currencies in the world, acting as a backbone for international trade and finances. It is estimated that two-thirds of the physical dollars in circulation are outside American territory. Besides the U.S. and its territories, eight sovereign nations have the U.S. dollar as their official currency, with several more accepting it as legal tender.
