Oatmeal - Everything You Wanted to Know about Oats:
"Oats are the third leading cereal crop produced in the United States (after wheat and corn) and the fourth most important crop world-wide. They were once considered a weed which grew right with the barley and wheat. One day farmers decided to 'join 'em rather than fight 'em,' and oats started being planted as a crop by itself. It fares best in cool, moist climates, which is why they are such a popular staple of the British Isles like Scotland, Ireland and Wales. The grain was introduced into the Americas in 1602 by a sea captain who planted them in one of the islands off the coast of Massachusetts. They were a popular grain, but corn had a better yield per acre crop, so their popularity wasn't as great as corn. Today, nearly half of the world's oat crop--more than 4 billion bushels a year--is grown in the United States and Canada."
