Their minds eventually changed, however, and in 1938 a Midwestern theater owner named Glen W. Dickinson Sr. installed popcorn machines in the lobbies of his Dickinson theaters. Popcorn was making more profit than theater tickets, and at the suggestion of his production consultant, R. Ray Aden, Dickinson purchased popcorn farms and was able to keep ticket prices down. The venture was a financial success, and the trend to serve popcorn soon spread. In 1970, Orville Redenbacher's namesake brand 
Title: Popcorn maker
Content:   A popcorn maker (also called a popcorn popper) is a machine used to pop popcorn. Since ancient times, popcorn has been a popular snack food, produced through the explosive expansion of kernels of heated corn (maize). Commercial large-scale popcorn machines were invented by Charles Cretors in the late 19th century. Many types of small-scale home methods for popping corn also exist. Commercial popcorn machines are commonly found in movie theaters and carnivals, producing popcorn in a pan of hot oil, so that approximately 45% of the calories are derived from fat. Hot-air popcorn poppers for home use appeared the late 1970s; these produce popcorn with only 5% of its calories derived from fat. The majority of popcorn sold for home consumption is now packaged in a microwave popcorn bag for use in a microwave oven. As a result, the popularity of popcorn makers for home use has greatly decreased in the last few decades.

Although small quantities can be popped in a stove-top kettle or pot in a home kitchen, commercial sale of freshly popped popcorn employs specially designed popcorn machines, which were invented in Chicago, Illinois, by Charles Cretors in 1885. Cretors successfully introduced his invention at the Columbian Exposition in 1893. At this same world's fair, F. W. Rueckheim introduced a molasses-flavored "Candied Popcorn", the first caramel corn; his brother, Louis Ruekheim, slightly altered the recipe and introduced it as Cracker Jack popcorn in 1896. Cretors's invention introduced the first patented steam-driven popcorn machine

Cretors, a Chicago candy store owner, had created a number of steam-powered machines for roasting nuts and applied the technology to the corn kernels. By the turn of the century, Cretors had created and deployed street carts equipped with steam-powered popcorn makers. During the Great Depression, popcorn was fairly inexpensive at 5–10 cents a bag and became popular. Thus, while other businesses failed, the popcorn business thrived and became a source of income for many struggling farmers, including the Redenbacher family, namesake of the famous popcorn brand. During World War II, sugar rations diminished candy production, and Americans compensated by eating

Content:   Popcorn is a popular snack food at sporting events and in movie theaters, where it has been served since the 1930s. Cinemas have come under fire due to their high markup on popcorn; Stuart Hanson, a film historian at De Montfort University in Leicester, once said, "One of the great jokes in the industry is that popcorn is second only to cocaine or heroin in terms of profit." Traditions differ as to whether popcorn is consumed as a hearty snack food with salt (predominating in the United States) or as a sweet snack food with caramelized sugar (predominating in Germany). Popcorn smell has an unusually attractive quality for human beings. This is largely because

Content:  Samuel M. Rubin (May 24, 1918 &ndash; February 5, 2004) was a concessionaire and businessman. He is best known for introducing popcorn to movie theaters in New York in the 1930s, earning him the nickname "Sam the Popcorn Man". He sold pretzels at age 6 and flags at 9. He started selling popcorn in Long Island City, New York and then at the age of 12 starting selling in theaters. He is the probable pioneer of the widespread use of popcorn machines in theaters. Rubin got the idea after watching popcorn being made in Oklahoma City around 1930. There is some uncertainty about whether Rubin was the first to sell popcorn

Content:  for snack food, Cretors redesigned his machine to roast peanuts and pop popcorn at the same time. It was the first automated machine that could pop popcorn uniformly in its own seasonings, guaranteeing a predictable product. Cretors applied for a patent on his automated peanut roaster and popcorn popper machine on August 10, 1891, and U.S. Patent 506,207 was granted on October 10, 1893. Cretors took his new popcorn wagon and peanut roaster to the midway of Chicago's Columbian Exposition in 1893 and introduced the new corn product to the public in a newly designed machine that included a popcorn wagon.

One theater company in Kansas City had about 4000 acres producing popcorn, and an unnamed person commented "Find a good popcorn location and build a theater around it." The health benefits of this cinema food are generally low, and have been debated for years. Owner of Sony Pictures, Michael Lynton, has been one of the chief arguers over this, and has wanted cinemas worldwide to stop providing this junk food and instead provide healthier alternatives, like crudités, smoothies, nuts, granola bars and additive-free air-popped popcorn.

In 1981, General Mills received the first patent for a microwave popcorn bag; popcorn consumption saw a sharp increase, by tens of thousands of pounds, in the years following. At least six localities (all in the Midwestern United States) claim to be the "Popcorn Capital of the World;": Ridgway, Illinois; Valparaiso, Indiana; Van Buren, Indiana; Schaller, Iowa; Marion, Ohio; and North Loup, Nebraska. According to the USDA, corn used for popcorn production is specifically planted for this purpose; most is grown in Nebraska and Indiana, with increasing area in Texas. As the result of an elementary school project, popcorn became the official state snack food of Illinois.
