Cheerios turn 70; Iconic cereal endures, sells

Here's a breakfast table quiz: What is the most popular cereal brand in American grocery stores?

Hint: It's been General Mills' top name since 1951.

Another hint: If you're a parent, you've vacuumed it from the minivan and under the high-chair cushion by the cupful.

The answer: Cheerios.

The cereal, known by its yellow box, is 70 years old this year and still a force on the breakfast cereal market. One out of every eight boxes of cereal to leave the shelf in America carries the Cheerios name.
