It’s 1904 and Quaker Oats is about to make an, ahem, explosive entry into the cold cereal business. With the Kellogg brothers at risk of being left behind, Will Kellogg finally decides it’s time to stand up to his brother. He cuts ties and brings the original corn flakes to market — aided by some shrewd advertising and an army of housewives — but sets off a legal battle that pits brother against brother. But there’s about to be another entrant to the cereal business. General Mills is an upstart out of Minneapolis with an idea for a new cereal that will help the company stand out from the competition. The donut-shaped oat puffs even have a catchy name: Cheerioats.
