In 1938, Glen W. Dickinson Sr., a Midwestern theater owner, installed popcorn machines in his Dickinson theaters. This decision, suggested by his production consultant R. Ray Aden, was driven by the profitability of popcorn, which allowed Dickinson to keep ticket prices low. This venture marked the beginning of popcorn's widespread popularity in theaters.
The Orville Redenbacher's popcorn brand was launched in 1970.
In 1981, General Mills received the first patent for a microwave oven popcorn bag, leading to an increase in popcorn consumption.
In 1998, hybrids of popcorn that produce 100% mushroom flakes were developed. Mushroom flakes, known for their ball-like shape, are less fragile than butterfly flakes and are often used for packaged popcorn or confectionery.
