Popcorn recipes come in many flavours, including salted, caramel, cheese, and butter, and dominate movie nights and theatres with their mouthwatering aroma. To get into the history of popcorn, one needs to go to the roots, to the place where corn was growing wild in yesteryears. It goes back 6,700 years to coastal Peru, making it one of the oldest prepared foods in the Americas.
The story of popcorn goes beyond its commercial success as a snack in movie theatres, and before that, it used to thrive in the arid northern coast of South America, which is now Peru. Excavations at two ancient settlements, Paredones (Chile) and Huaca Prieta (Peru), unearthed corncobs, husks, stalks, and tassels dating to between 6,700 and 3,000 years ago. Published in the Proceedings of the National Academy of Sciences, the research confirmed these as the oldest corn remains ever found in South America. It turns out that people living there were already popping corn, around 1,000 years earlier than previously estimated.
This predates the use of ceramic pottery at those same sites. The popcorn recipes from back then were quite simple: a cob would be wrapped in some material and either rested on coals, roasted over an open flame, or cooked in earthen ovens. Corn was not a dietary staple back then; it was likely a delicacy.
Corn had arrived in South America from Mexico (Zea mays everta), where it was first domesticated from a wild grass called teosinte, the ancestor of modern maize, approximately 9,000 years ago. Teosinte was known to sustain its local population, having kernels that were too hard to grind or even eat.
The locals figured out it would burst once heat was introduced, with the kernel's starch acting as moisture under pressure. It didn’t take long for it to become a food source. It used to be a challenge to grab the popcorn as it popped in the heat. By 5000BC, this wild corn had begun to be domesticated.
Trade and migration routes made corn spread northward across Central America and into what is now the United States. By the time European explorers arrived in the Americas, Native American communities had developed approximately 700 varieties of corn, including those with stiff kernels, which were behind popcorn recipes that popped.
Popcorn was quite important to the Aztecs, who called it momochitl, and they used it as both food and decoration. They even coined a term for the sound the popcorn made as it emerged from the kernel – it was totopoca! The women of the tribe performed a popcorn dance, wearing thick tassels made of popcorn around their heads during ceremonies. Popcorn garlands were also adorned on the God of rain and fertility, Tlaloc.
Spanish explorer Hernán Cortés came across popcorn in 1519, when he encountered the Aztecs, as found in one of the earliest written European accounts of the snack. The oldest ears of popcorn found in North America were discovered in Bat Cave, New Mexico, in 1948 and 1950, and date to approximately 5,600 years ago. In Peruvian tombs on the east coast, researchers have found preserved popcorn grains estimated at around 1,000 years old, still intact and identifiable as popcorn.
Until the late 1800s, in American history, corn was grown by families for popcorn or traded within communities, and was not yet a cash crop. That changed around 1890, when demand shifted enough for popcorn to become a proper market crop. The primary growing regions were, and remain today, Nebraska, Iowa, and Indiana, where the heat creates ideal conditions for popcorn.
Popcorn recipes were not yet popular, but the phrase ‘popped corn’ first appeared in print in 1848 in an American publication. From there, poems and advertisements took off, and their popularity only grew with time. A turning point for popcorn came in 1885, when Charles Cretors, a candy maker based in Chicago, built the world's first mobile popcorn machine. It weighed around 200 kg and could be moved on wheels by a pony.
Cretors debuted his machine at the World's Columbian Exposition in Chicago in 1893, and was issued a street peddler's licence to operate it publicly as early as December 1885. The machine changed everything about popcorn's place in urban life. By the turn of the 20th century, popcorn carts had become a common fixture at fairs, circuses, sporting events, and street corners across American cities.
When movie theatres arrived and grew in the early 20th century, owners actively resisted popcorn. The spaces were modelled after traditional theatre, with some having beautiful carpets, ornate interiors, all of which were classy, that popcorn’s street food label couldn’t quite match.
The popcorn machine was inconvenient and occasionally produced an unpleasant burning smell; aside from that, it was crunchy and messy. Theatres back then used to post signs instructing patrons to check their popcorn containers with their coats. The shift happened in 1915, when a Kansas City widow named Julia Braden negotiated with the Linwood Theatre to set up a stand. By the time the Great Depression hit, she had built a small concession empire.
After 1929, movie theatres, which had been among the last remaining affordable luxuries for most Americans, faced financial pressure. The shift from silent films to talkies had already broadened the audience. Now, with theatres struggling to stay solvent, operators began leasing lobby space to vendors for as little as $1 a day, then eventually installing their own popcorn machines.
The snobbish behaviour towards popcorn was still prevalent during the Great Depression. A Dallas theatre chain installed machines in 80 of its cinemas but refused to do so in its premium locations. Within two years, the theatres with popcorn saw profits rise steeply, while the premium ones suffered losses. By 1938, one 66-theatre chain reported a loss on ticket sales but a profit of nearly USD 200,000 on popcorn alone. Popcorn was as cheap as 5 to 10 cents a bag, affordable even during the Depression, with theatres still making substantial profits. By the 1930s, concession counters had become a fixture in newly constructed cinemas.
When Japan's conquest of the Philippines in early 1942 cut off one of the United States' primary sugar sources of sugar. It became the first rationed food item in the country, with household allocations reduced to eight ounces per week by 1945. Candy and sodas largely disappeared from theatre concession stands.
Popcorn was already a popular item by this time and required no sugar. It was cheap, it was grown domestically, so it filled the void immediately. Data show that Americans consumed three times as much popcorn as usual during the war years. By 1945, nearly half of all the popcorn grown in America was being eaten in movie theatres.
The 1950s brought a major change as television began to be installed in American homes. This marked the era of staying in, as people preferred watching television to going out to movies. But somehow, popcorn managed to survive, as people still wanted something to eat while watching television, and it moved right in. Popcorn recipes shifted to the stovetop, popped with oil instead of using machines.
It was also during this era that popcorn started to be branded as a product. An agricultural scientist from Indiana named Orville Redenbacher was behind this. In 1952, this researcher worked with a group of family farmers to grow a special kind of corn. He and his business partner, Charles Bowman, launched Redenbacher’s crossbred hybrid popcorn kernel that popped into larger, fluffier popcorn than anything commercially available in 1969.
It went national in 1973, and Redenbacher sold the brand to Hunt-Wesson in 1976. What Redenbacher and Bowman had done was establish the concept of ‘gourmet’ popping corn, which is the very idea behind popcorns today, to boost its appeal among the countless food options at movie theatres. When presented with a better option, consumers would want to pay more for higher quality, as has been the case with popcorn.
The invention that moved popcorn from an occasional preparation to a household staple was the microwave popcorn bag. Its origins trace back to Percy Spencer, the engineer who invented the microwave oven, who filed a patent for a microwave popcorn popping bag in 1947, although commercial development took decades.
1947: Percy Spencer patents the concept of popping corn using microwave radiation.
1981: The first shelf-stable microwave popcorn bag patent is filed, enabling retail distribution without refrigeration.
1981-1984: Act I (frozen) and Act II (shelf-stable) become early commercial milestones for microwave popcorn from Golden Valley Microwave Foods.
1983: Orville Redenbacher's launches its microwave popcorn line, using the susceptor-lined bag, which was a specially engineered packaging that absorbs microwave energy and crisps rather than steams the corn.
1987: Act II's shelf-stable format goes mainstream; Pop Secret, backed by a massive advertising campaign, captures the market by offering compatibility with all microwave wattages.
By the late 1980s, microwave popcorn had become a standard item in American grocery stores and, through the 1990s, in kitchens across much of the world. The VHS home video boom of the same era provided the consumption context: movie nights at home now had a built-in snack, and the association between films and popcorn extended from cinemas into living rooms.
Once microwave popcorn became a household staple, the snack industry began experimenting with possible flavours to add to their usual popcorn recipes. The typical cinema offering was salt and butter, but with time gave way to a wide range of preparations that reflected local taste and premium brands. Famous flavours of popcorn recipes today include:
Classic butter and salt: the cinema original, still the most widely consumed preparation worldwide.
Caramel popcorn: sugar-coated, oven-baked or stovetop-prepared; popularised by Chicago's Garrett Popcorn (established 1949), where the caramel-and-cheese ‘Chicago Mix’ became a signature.
Cheddar cheese: dry cheese powder coating, which is a major American snack category.
Masala popcorn: the Indian variation, using a combination of chaat masala, red chilli powder, amchur (dry mango powder), and black salt.
Caramel chocolate: premium popcorn and oriented towards gifting.
Truffle and parmesan: a gourmet positioning now common in speciality food retail
Sriracha and hot sauce variants: reflecting the trend toward spicy flavours
Corn used to grow wild, like Mowgli among the wolves in The Jungle Book; from being enjoyed as a rare food to being part of celebrations, like popped rice in many auspicious Hindu ceremonies; to hybrid varieties that produce the big, poofy popcorn, its journey has been a long one. Celebrate its history by making homemade popcorn using one of the many recipes in your favourite flavours.
