Popcorn! :P

Popcorn is not a modern food like potato crips. It is more than 5,000 years old. Popcorn was an American Indian food. Columbus bought popcorn necklaces in the West Indies. There was also popcorn at the first Thanksgiving meal in North America in 1621. In the 1940s, cinemas in the USA started to sell popcorn. It is still the most popular cinema snack. :D
