Frosted Flakes, Froot Loops and Raisin Bran. These are just a few of the popular cereals that made the Kellogg Company a global leader in breakfast. But over the decades Kellogg's has expanded far beyond cereal into a snack powerhouse as well, with brands like Pringles, Pop-Tart's and the fan favorite Cheez-It crackers. Trouble is, while its snack business was growing quickly, its cereal business was in decline. Last year, Kellogg's split in to two companies. Its North American cereal business is now a standalone company called WK Kellogg Co, and its snack brands and international cereals are run out of the newly formed Kellanova company. On this week's episode of Leadership Next, Kellanova CEO Steve Cahillane talks to Diane about the tough choice to separate the companies, why Pringles are a hit overseas, and the love affair between Cheez-It and Taco Bell.
