The defeat of Wall Street in 1929 and the subsequent economic crisis brought cinema and popcorn together. In the past, the habit of eating stuffy corn on the street had spread, but the silent film was still too elitist to allow a simple shooting in the halls.

Thanks to sound films, film became popular, but it was the crisis that introduced popcorn in theatres: cinema was one of the cheapest pastimes, maize was also cheap and popcorn was prepared very easily.

The relationship narrowed during the Second World War, as the sugar shortage left out candy and soft drinks. Since then, the binomial has faced television and microwave has been his ally.
