$125 million for a Grade-school math error

Image: Aaron Lefler

Imagine losing a hugely expensive spacecraft due to a simple mix-up between English and metric measurements . That is exactly what happened to NASA in 1999 when a Mars orbiter designed by Lockheed Martin was lost in space.

The confusion caused a malfunction on the $125 million craft, resulting in the probe’s loss. Although it was unusual for Lockheed to use English measurements for a NASA design (since NASA had stipulated using metric measurements for many years), there were still several instances where the error should have been caught but wasn’t.

Toys ‘R’ Us blunder

If you think an action figure of a drug dealer isn’t the best idea for a toy store , you’re not alone. Yet, for some reason, Toys "R" Us decided otherwise in October 2014, possibly hoping to cash in on the massive success of the Breaking Bad TV series.

Unsurprisingly, the giant toy retailer was forced to pull from its shelves four collectible dolls based on characters from the AMC hit show, each doll featuring a detachable sack of cash and a bag of meth.

Apple Maps' rocky beginnings

When Apple decided to launch its own map application on iOS devices after a conflict with Google in 2012, users quickly realized that the Apple app was not nearly as launch-ready as it should have been .

Locations were mislabeled, roads were missing, and it occasionally steered people in entirely the wrong direction. The problem was eventually, though largely, resolved, but it was an embarrassing misstep for a company known for never launching a product before it was as near-perfect as possible.

Bank of America debit card fee

Image: Ali Mkumbwa

Back in 2011, when the backlash against the banking industry had not yet reached its boiling point, Bank of America announced it would charge customers $5 per month to use their debit cards .

It was a bad business decision. More than 300,000 people signed an online petition, and Fox Business Network’s Gerri Willis cut up her debit card on air. The bank pointed to federal regulations as the reason for the charge but ultimately capitulated to consumer demand after a month before the fees went into effect.

$33 airline tickets from Toronto to Cyprus

If buying a business class ticket regularly priced at $2,558 for just $33 sounds too good to be true, it probably is. Except in 2006, when an Alitalia employee accidentally forgot to input two extra zeros when pricing business-class tickets from Toronto to Cyprus.

Due to the exchange rate on that day and the blunder, hundreds of buyers managed to snag fares for just $33. The airline honored those deals, accepting the heavily discounted price for the 509 people who purchased tickets before the error was detected.

A $70 million comma

As the folks at NASA and Alitalia have shown us, small errors can lead to costly mistakes. The following blunder comes courtesy of Lockheed Martin , which issued a contract to a customer with a missing comma in the sale price .

The astute customer held the aerospace company to the contract, costing Lockheed Martin $70 million for a C-130J Hercules aircraft in June 1999.

Sears misses the ship

A retail giant that faced a situation similar to the one Kodak faced—embrace the new and unknown or cling to the old, successful recipe—Sears sold everything from socks to tires via mail order, shipping across the U.S.

Choosing to stick with the old method, the company ended its catalog and delivery business in 1993 . In 1994, Amazon was founded , filling the business void that Sears had just created. The rest is history.

Passing on Microsoft

Image: Jaime Marrero

$60 million might seem like a lot of money to us regular folks, but for someone with very deep pockets like Texas businessman and two-time U.S. presidential candidate Ross Perot, it wasn’t all that much.

In 1979, he was offered the chance to buy Microsoft for that sum. However, his final offer to the tech company was just $15 million, and as a result, the Texan missed out on the opportunity to own what would become one of the biggest companies in the world .

Blackberry sticks with the old

Image: Thai Nguyen

Another case of a brand sticking with the old instead of embracing the new, BlackBerry was all the rage at the start of the 21st century— until Steve Jobs came along with the Apple iPhone .

While BlackBerry Messenger was extremely popular, with over 80 million users worldwide, the device lacked the new touchscreen functionality and sleek design of the Apple product. From being a market leader, BlackBerry’s market share plummeted to 0.2% by 2016.

RadioShack’s downfall

Image: Jelleke Vanooteghem

Not so long ago, RadioShack was a familiar presence on the streets and the go-to place for buying batteries and electronics. But it was that same brick-and-mortar presence, coupled with a reluctance to embrace e-commerce , that ultimately led to its demise .

Eventually, poor profit margins on what they could sell, combined with a loan they couldn’t repay, brought down what was once the go-to place for electronics.

Batman and Robin

Tom and Jerry

Joey and Chandler

In Friends , Joey Tribbiani and Chandler Bing gave us one of TV’s most memorable bromances. Between foosball games, recliner time, and their shared apartment antics, they showed the ups and downs of friendship in a way that felt real. Through every argument and every laugh, they stayed best buds.

Corn Flakes

Who hasn't started their day with a bowl of Corn Flakes at least once? While Corn Flakes weren't exactly the first packaged cold cereal product sold in America, they are undoubtedly the most iconic. As early as 1902, William Keith Kellogg began mass production of his first cereal after proving its efficacy and popularity with patients at the Battle Creek Sanitarium, where he worked alongside his prestigious doctor brother.

The Kellogg brothers were focused on offering a healthier alternative to the traditional pork-and-beef heavy English-style breakfasts that most Americans were eating at the end of the 19th century. Therefore, they developed a process that allowed them to transform thin slices of cereal into small toasted flakes of wheat or corn. Since then, Corn Flakes, combined with fresh milk, have been one of the most popular breakfasts among Americans, young and old.

Cheerios

Did you know that a one-ounce serving of Cheerios contains nearly 250 individual "O's."? Crazy, right? Introduced in 1941 by the American company General Mills, Cheerios is one of the first oat-based ready-to-eat cereals and remains one of the most widely consumed in the United States.

Back in the 1930s, General Mills engineers tested more than 500 formulas and experimented with 10 different shapes and sizes before perfecting the now-iconic "O." They finally came up with the delicious cereal that offers the nutrients of 4 cereals: oats, corn, wheat, and rice. Today, there are about 20 different flavors of Cheerios available in the U.S., including Honey Nut, Chocolate, and Apple Cinnamon. Which one is your favorite?

Rice Krispies

Kellogg’s is one of the most influential breakfast cereal companies in the United States and the world, and we have them to thank not only for Corn Flakes but also for our beloved Rice Krispies. This breakfast cereal made from crispy rice first appeared on the shelves in 1928. It was revolutionary at the time because the company used a new patented process called "oven-popping" to manufacture them.

Rice Krispies’ success may have been due to its claim that the cereal would remain floating even after 2 hours in milk. The brand's classic slogan honoring this unique quality—"Snap! Crackle! Pop!"—was introduced around 1939 and is still used on packaging today. For decades, Rice Krispies has been one of the most popular cereals among consumers, so much so that even the Rolling Stones recorded a short song for a television commercial promoting the brand in 1964. Do you remember the catchy tune?

Cap'n Crunch

Image: Samantha Gades

Cap'n Crunch cereal, a combination of corn and oats, was developed in the early 1960s by Pamela Low, a flavorist who was inspired by a brown sugar and buttered rice recipe from her grandmother. Since its debut, additional flavors have been introduced, including Berries, Peanut Butter, and Chocolate.

But did you know that Cap'n Crunch’s full name is Horatio Magellan Crunch ? The iconic cartoon mascot was developed for the Quaker Oats Company by Allan Burns, a screenwriter and television producer who later co-created popular shows like The Munsters and The Mary Tyler Moore Show . Since its introduction in 1963, the late 18th-century naval captain, born on Crunch Island—a magical land in the Sea of Milk—has won the hearts (and bowls) of countless consumers across America.

5

Trix

Image: Sascha Bosshard

General Mills introduced Trix in 1954 as the first fruit-flavored cereal. Initially, it wasn’t marketed exclusively for kids, but because of the bright colors, it soon became a favorite among the little ones. When Trix was first launched, it featured round cereal balls in three flavors: "Raspberry Red," "Orange Orange," and "Lemony Yellow." It wasn't until 1991 that Trix became the first fruit-shaped breakfast cereal.

But as with other brands on this list, Trix is best remembered for its mascot rather than the cereal itself. In fact, the Trix Rabbit is one of the single longest-running ad campaigns in television history. Since the 1960s, the brand has kept the same character, the same slogan—"Trix are for kids!"—and the same storyline: the rabbit’s endlessly thwarted attempts to steal a box of cereal.

6

Frosted Flakes

Image: Engin Akyurt

If we talk about the sweetest cereals on the market, we cannot fail to mention Frosted Flakes. The concept and technology of a "frosted" cereal was developed in 1939 by Jim Rex, a salesman from Philadelphia who unfortunately didn’t have much success with his product Ranger Joe Wheat Honnies. The idea, though, was soon adopted by the breakfast cereal industry, and by 1952, Kellogg introduced Sugar Frosted Flakes to its lineup.

That same year, Kellogg launched a campaign featuring Tony the Tiger, Frosted Flakes’ famous mascot, who proudly declared, "Sugar Frosted Flakes are Grrr-reat! The slogan and the character became so popular in the United States that it's probably more quintessential than the cereal itself.

7

Lucky Charms

Image: Céline Druguet

The mini marshmallows found in Lucky Charms, whose technical and copyrighted name is Marbits , were invented, along with the cereal, by General Mills product developer John Holahan in 1963. One morning, he cut up a few orange marshmallow Circus Peanuts, mixed them into a bowl of Cheerios, and was delighted with the result. The rest, as they say, is history.

Lucky Charms is inspired by Irish culture. Its mascot, Lucky the Leprechaun debuted on St. Patrick's Day in 1964. The successful combination of this endearing character, delicious shaped oat pieces, and colorful little marshmallows was quickly embraced by children around the world. Tasty, crunchy, and fun, this cereal has undeniably revolutionized American breakfasts forever.

8

Froot Loops

Toucan Sam has been a part of our lives for more than 60 years now. Kellogg’s iconic mascot—a blue, anthropomorphic toucan with the ability to smell Froot Loops from great distances—was introduced alongside the O-shaped cereal in 1963.

Froot Loops were developed after Kellogg attempted to displace General Mills' Cheerios from the market. The idea of introducing fruity flavors proved to be a success, even though, years later, the company admitted that the different colors did not correspond to unique fruit flavors. In recent years, Froot Loops have faced criticism for their use of artificial colorings and high sugar content. Yet, they still have plenty of fans and they remain one of the best-selling cereal brands in America.

9

Cinnamon Toast Crunch

Another popular breakfast cereal created by General Mills is Cinnamon Toast Crunch. In fact, the company sells over 100 million boxes a year of this brand alone, putting it just behind Cheerios and Frosted Flakes in sales. How about you—do you have a box of Cinnamon Toast Crunch waiting in your pantry?

These delicious little squares of whole wheat and rice, topped with cinnamon and sugar, were first launched in 1984 and were an instant hit. And it makes sense, given that, in a way, they were invented by a child. Cinnamon Toast Crunch was developed by General Mills scientists and product managers after an unnamed child suggested the idea of a cinnamon toast-flavored cereal during a radio contest. Since then, it has remained one of America's favorite cereals and we don't expect its popularity to wane any time soon.

Life

More than 60 years after its creation, Life remains one of the top 10 best-selling cereal brands in the United States. Introduced on the market in 1961 by the Quaker Oats Company under the slogan "The most useful protein ever in a ready-to-eat cereal," Life is a multigrain cereal enjoyed by millions of family households across the country.

Like its competitor Trix, Life has also made history in marketing and advertising. A famous Life commercial featuring Little Mikey, a hard-to-please four-year-old boy, aired nationally from 1972 to 1984, making it the longest-running commercial in television history . Have you seen it? We bet you have!
