Popcorn is no pop culture fad but a snack that's over 5,000 years old. But it became an integral part of cinema theatres during the early 20th century. Popcorn vendors set up stalls outside theatres.
While theatre owners considered them a nuisance, these vendors attracted moviegoers by the dozen. Theatre owners thought it a good proposition to ask them to set up stalls inside the premises in return for a portion of their sales.
Eventually, popcorn vending machines made their appearance and the snack has ever since been associated with movies.
