How Popcorn Snuck Into the Movies

The quintessential theater snack was originally banned

Have you ever been to a movie theater and not eaten popcorn? For many, the idea is unimaginable — movies and popcorn go hand in buttery hand. But there was a time when popcorn was banned inside movie theaters.

That’s right. The default snack was once treated like contraband — too messy, too noisy, too low-class for a respectable theater.

Popcorn’s journey from banned outsider to ubiquitous snack was a combination of the anxiety of theater owners, the Great Depression, and a scrappy Kansas City widow.

Popcorn is a specific strain of corn, one with especially starchy kernels and hard walls that when heated let pressure build until they burst. Indigenous peoples in what is now southern Mexico were cultivating it from a tall grass called “teosinte” thousands of years ago, and tribes across the Americas worked out their own ways of popping it. Some tossed kernels straight into the fire and grabbed the ones that flew out.

By the mid-1800s it had caught on across America. People began using wire baskets with long handles to hold kernels over a flame, but they cooked unevenly. The real turning point came in 1885, when Charles Cretors of Chicago invented the first steam-powered popcorn machine. Suddenly popcorn could be made quickly and inexpensively — no kitchen required.

Popcorn was everywhere: fairs, circuses, ballparks, street corners. Everywhere, that is, except one place.

Movie theaters wanted class

The lavish movie palaces of the 1910s and 1920s were grand places. Owners wanted a refined clientele, and they didn’t want a messy lowbrow snack to interfere with the grand feel.

As popcorn historian Andrew Smith put it, movie theaters “wanted nothing to do with popcorn” because they were trying to copy real theaters, which had beautiful carpets and marble lobbies. Crunching also meant noise, which, actually, was a real problem in the silent-film era. With no soundtrack to muffle the noise of crunchy popcorn, all you could hear was the sound of snacking. So the theaters simply banned it. When street vendors parked their popcorn carts right outside the theaters and sold the snack to moviegoers heading in, many theaters fought back. Some actually hung signs by the coatroom asking patrons to check their popcorn along with their coats.

The Kansas City widow who saw it first

It was Julia Braden who played a key role in popularizing popcorn as a quintessential movie snack.

She’d already worked as a traveling saleswoman peddling medicine, lotions, and ink across the Midwest before settling in Kansas City around 1900 and starting in the popcorn, peanut, and candy business. By the time she wanted to try a new spot to sell popcorn — the movie theater — she’d built a small empire of popcorn stands branded and duly registered as “Braden’s Golden Flake Popcorn,” complete with newspaper ads warning that “any infringer [of the trade mark] will be prosecuted.” By her own account, she worked 16 hours a day for 16 years.

And it wasn’t just Braden. The 1930s changed everything. Money was tight during the Great Depression years, and the movies were one of the few affordable escapes left. A ticket cost around 20 to 25 cents between 1930 and 1933 (roughly $4 to $6 in today’s money), and for that you could forget your troubles for two hours.

The exact deal she struck with the Linwood Theatre is either lost or not documented, but by 1931 Braden was running four stands in or near Kansas City theaters and pulling in more than $14,400 a year — over $300,000 in today’s money. Her popcorn business kept growing right through the worst years of the Depression — even as thousands of movie theaters across the country were closing their doors.

For theater owners, the math was tempting. A bag of popcorn that sold for a nickel cost the theater less than a penny to make. Ticket money mostly went back to the studios, but popcorn money stayed at the theater. The snack wasn’t a side hustle anymore. It was the business.

But eventually theater owners had the obvious realization: they too could make profit by selling popcorn. First they leased lobby privileges to vendors like Braden for a daily fee. But soon they opened their own concession stands.

About a third of all American movie theaters — roughly 7,000 of them — closed between 1928 and 1935, according to Prof. Richard Butsch’s research on Depression-era audiences. But popcorn-refusal wasn’t the main thing killing them. The Depression hit independent theaters in rural and working-class areas hardest. The Hollywood Reporter has documented similar closure figures in its own reporting on the era.

What popcorn — and concessions more broadly — did do was rewrite the survival economics for the theaters that adapted. As Rider University’s Butsch puts it, the movie palaces that survived in the 1930s “redefined the evening from one of champagne to one of popcorn and soda.” In his book Popped Culture: A Social History of Popcorn in America — which appears as source to many articles on popcorn’s history — he argues that popcorn specifically did most of that heavy lifting, and he cites two cases to support him. One Dallas theater chain, Interstate Theaters, that installed popcorn machines in 80 of its theaters — but kept them out of its five “high class” venues — watched the 80 turn a profit and the five tip into red within two years. R. J. McKenna, who ran a separate 66-theater chain in the West, was “staunchly anti-popcorn” until his losses forced him to change: by 1938, his theaters had lost money on tickets but made nearly $200,000 on popcorn sales alone.

One more twist sealed the deal. During World War II, sugar was rationed, and candy and soda — both sugar-dependent treats — became scarce. But popcorn stayed cheap, plentiful, and salty. By 1945, more than half of all the popcorn eaten in America was being eaten at the movies.

The habit was now unbreakable — and theaters leaned all the way in. In 1957, theaters started nudging moviegoers toward the snack counter with the cheerful animated jingle “Let’s All Go to the Lobby,” with its singing, dancing popcorn box, soda cup, and candy bar. It became so woven into American moviegoing that in 2000 the Library of Congress added it to the National Film Registry — the same honor given to films like It’s a Wonderful Life.

Why it still works, every single time

Popcorn prevailed because it checks every box. It’s cheap to make, easy to sell, profitable, portable, and — crucially — edible in the dark with one hand while the other clutches your armrest during a scary scene. Try doing the same thing with a dripping ice cream cone. Or a steak.

With the buttery smell of popcorn drifting through every theater’s lobby, most of us are hit with the craving before we ever reach our seats.

And popcorn is still the financial backbone of the movie theater business. The margins of profit have mostly remained the same. Today’s numbers are eye-popping too: a $6 bag of theater popcorn costs about 60 cents to produce — a markup of roughly 1,000 percent. Prices vary in different locations but industry estimates put concession sales at around 40% of a theater’s overall profits.

So the next time the lights dim, the trailers roll, and someone nearby starts eating popcorn, remember, the bag of popcorn could have meant no entry about a hundred years ago. Now, theaters depend on it.
