General Mills tried to make what salty '60s snack into a cereal?
Over its long history, General Mills has tried producing many different kinds of cereal. Its research department invented both an inexpensive way of producing vitamin D and a proprietary “puffing gun,” which resulted in two of its early successful cereals, Kix and Cheerios. Today, the company produces such classics as Lucky Charms and Wheaties — but not every cereal has stood the test of time. In the 1960s, General Mills tried to turn its salty Bugles snack into a cereal called Cornados. It wasn’t a hit with consumers, and today, most General Mills cereals are sweet, not salty.
