WHAT’S A FILM WITHOUT POPCORN
Popcorn has been associated with cinemas and films for as long as we can remember. But where did this connection begin and will it carry on into the future?
Popcorn became a popular snack food in North America in the 19th century and was sold at circuses and fairs. No kitchen was needed to prepare it and once the mobile steam owered popcorn maker was invented, it became possible to mass produce the snack. Popcorn had an appealing smell when popped and this attracted many people to buy it.
In the 1930s, people began flocking to the cinema but at first, popcorn was not sold inside the cinemas. Cinema owners wanted to protect the costly carpets that they had put in their cinemas. They were also concerned that the sound of people eating snacks would disturb the other people watching the film. So, enterprising salesmen set up popcorn machines outside the buildings. As lots of people began buying popcorn on their way into the cinema, cinema owners understood that they could make money from the popular snack. Thus, they decided to allow the salesmen to sell popcorn in the cinema lobby for a daily fee. Eventually, cinemas began selling snacks themselves. This decision helped save many of the cinema owners from going out of business.
Today, popcorn is still economically important to cinemas. Because popcorn is so cheap to make, cinemas make a lot of profits on every box they sell. Yet, there are those that suggest that popcorn in cinemas may be on its way out. In recent years, luxury cinemas have become increasingly popular. These cinemas try to give people a more “exclusive” experience by serving gourmet food in addition to traditional popcorn.
Yet despite this development, it is unlikely that popcorn will vanish completely from cinemas. For many of us, eating popcorn is an integral part of the experience of watching a film. Even when 38 we watch a film on TV at home, we often make ourselves some microwave popcorn. Old habits, it seems, are hard to break!
