Short answer: nobody invented popcorn. It is a wild grass that learned to explode thousands of years before anyone wrote anything down. What people did invent, much later, was the machine that turned an ancient food into the snack you smell at a ballpark. That machine has a name and a date, and so does the man who built it.
We have been popping corn in Phoenix since 1998, so we get this question a lot at the stand. Here is the honest version.
The one-sentence answer
Popcorn was not invented by a person. It is a natural variety of maize, and archaeologists have found popped kernels more than 5,000 years old. The modern popcorn machine, the one that made popcorn a business, was invented by Charles Cretors of Chicago in the 1880s.
Both halves of that sentence matter, so let us take them one at a time.
Popcorn is older than written history
Corn did not always look like the yellow ears you buy in summer. People in what is now Mexico domesticated it from a wild grass called teosinte around 10,000 years ago. One type of that early corn had a hard shell and a soft, starchy center, which is the exact recipe for a kernel that pops.
When you heat one of those kernels, the water trapped inside turns to steam. Pressure builds against that hard shell until the whole thing turns inside out. That is popcorn, and it has been happening for a very long time. Researchers have turned up popped kernels and old popping tools at sites across the Americas that date back thousands of years, which makes popcorn one of the oldest snacks humans have ever eaten.
So the next time someone tells you popcorn is junk food, you can tell them it predates the wheel in this part of the world.
How people popped it before there were machines
Ancient cooks did not have kettles or hot-air poppers. They had fire and patience. The common methods were simple: heat an ear of corn near the coals until the kernels burst right on the cob, or toss loose kernels onto a bed of heated sand or a hot clay pan and catch them as they jumped.
Popcorn also showed up in ceremonies and decoration, not just as food. It was strung, worn, and used in celebrations across the Americas long before it landed in a paper bag.
By the mid-1800s, popcorn had a written record in English and a growing fan base in the United States. It was cheap, it stored well, and it was fun to make. All it needed was someone to figure out how to sell a lot of it, fast.
Charles Cretors and the machine that changed everything
That someone was Charles Cretors. In 1885 he was a candy-store owner in Chicago who was not happy with the peanut roaster he had bought, so he rebuilt it. What he ended up with was a steam-powered machine that could pop corn evenly in oil and seasoning, out on the sidewalk, in front of a crowd.
He put it on a wagon. That was the trick. Now the popcorn came to the people, at fairs, circuses, and busy street corners, and the smell did the selling. Cretors showed his steam popper at the 1893 World's Columbian Exposition in Chicago, and the mobile popcorn business was born. The company he started is still around today.
This is why Cretors, not any single ancient farmer, gets called the inventor of popcorn. He did not invent the food. He invented the way we buy it.
How popcorn became an American habit
A few things turned popcorn from a novelty into a staple.
It was cheap during hard times. Through the Great Depression, a bag of popcorn cost about a nickel, which made it one of the few treats families could still afford.
It found a home at the movies. Theater owners noticed that popcorn was profitable and that the smell pulled people in, so the snack and the silver screen grew up together.
It got a wartime boost. When sugar was rationed during World War II and candy got scarce, Americans ate even more popcorn to fill the gap.
Put those together and you get the snack we know now, sold at stadiums, theaters, fairs, and, in our case, a food trailer parked outside Chase Field.
Our small corner of popcorn history
We are not going to pretend Cactus Corn invented popcorn. We showed up in 1998, which in popcorn years is last Tuesday. But we have spent 28 years doing our part of the story: popping fresh corn at Chase Field since 1998, with 25,000+ bags sold at State Farm Stadium in the 2025 season, and turning a snack older than history into something that tastes like the Southwest.
Prickly pear on kettle corn. Roasted street corn with a little heat. Real jalapeño and white cheddar. That is popcorn's long history meeting our corner of the desert.
If reading about popcorn made you hungry for some, that is the correct response. Grab a Variety 12-Pack and taste six flavors at once, or send someone an Arizona popcorn gift tin with a little history baked in.
Frequently asked questions
Who invented popcorn?
No single person invented popcorn. It is a natural variety of maize that Indigenous peoples of the Americas were popping more than 5,000 years ago. The modern popcorn machine was invented by Charles Cretors of Chicago in 1885.
Who invented the popcorn machine?
Charles Cretors built the first steam-powered mobile popcorn machine in Chicago in 1885 and showed it at the 1893 World's Columbian Exposition. His design is the reason popcorn became a street and fairground business.
How old is popcorn?
Archaeologists have found popped kernels and popping tools thousands of years old, with some evidence pointing past 5,000 years. Corn itself was domesticated in Mexico around 10,000 years ago.
Where was popcorn first made?
In the Americas. Corn was domesticated in what is now Mexico, and early popcorn use has been documented across Mexico, the American Southwest, and South America.
Why does corn pop?
Each kernel holds a bit of water inside a hard shell. Heat turns that water to steam, pressure builds, and the kernel bursts and turns inside out. Only certain varieties of corn have the right shell to do it.
