Cheetos are a crunchy, cheese-flavored snack made from extruded cornmeal. Introduced by Frito-Lay in 1948, currently about one billion bags are sold worldwide each year. In some markets they are popular enough that the word "Cheetos" is often used as a genericized trademark for any similar cheese puffs snack food, but it is, in fact, trademarked by the Frito-Lay company.
