The cereal tinkerers who invented Cheerios 71 years ago needed only one variety, the yellow-box original that remains a staple of American breakfast tables.
They would barely recognize what their humble oat concoction has become: a General Mills franchise that has grown to encompass 13 varieties, with five added in just the past three years.
The latest arrived this winter: Dulce de Leche and Multi Grain Peanut Butter.
Cereal is what marketers call a "variety-seeking" category, driving Golden Valley-based General Mills and its competitors to continually put new offerings on the shelves.
"Most people don't want the same thing every morning," said Jeff Harmening, president of General Mills' Big G cereal division. Yet "with a category as old as cereal it's a challenge to find something really compelling and new."
So cereal makers increasingly rely on the less risky practice of extending key brands, and none more so than Cheerios. General Mills started in the 1970s, most notably with Honey Nut Cheerios, but has ramped up the pace in recent years with frequent new introductions.
The addition in January of Dulce de Leche and Multi Grain Peanut Butter gave the company more varieties than ever.
"What's developing now in the [cereal] category is the megabrand," said Rick Shea, owner of Shea Marketing, a Chanhassen-based food industry consultancy. With Cheerios, for instance, "oat circles" have essentially become a manufacturing platform, he said.
