137 years ago, John Henry Kellogg took over the Battle Creek Sanitarium and his brother (WK Kellogg) acted the bookkeeper for the place.
Not content with just helping the folks, the brothers began experimenting with the diet program. (And, they were very pro vegan diet, to boot.) By 1894 (18 years later), either they invented corn flakes or stumbled upon the right formula by leaving their concoction overnight (which would make this a serendipitous discovery). [There is a humorous, semi-historical (but not quite hysterical) account of the genesis of the firm, written by T Coraghessen Boyle (The Road to Wellville.) I recommend this book to you.] 
By 1906, the Kelloggs were running the Battle Creek Toasted Corn Flake Company; unfortunately some 15 months later (4 July 1907), the plant was destroyed by a fire. WK Kellogg reconstructed the plant within four months and had his brother agree to relinquish control to himself, which led to the formation of Kellogg Toasted Flake Company (eventually becoming the Kellogg Company in 1922.
Over the decades, Kellogg expanded it’s breakfast cereal offerings and developed a whole line of snacks (aka junk food) we could enjoy. Which is where the ‘perceived’ problem is nowadays.
Investors are not excited about the cereal group- it’s not sexy enough, it’s not growing fast enough, etc. Which led the Kellogg company to consider splitting into three groups. But, now they realize that the best strategy (something we will follow for the next year or two) is to split the company into two groups. (The third group was to have been the plant-based, synthetic meat group- and like many of those groups, it is not performing very well.)
The snack group will become known as Kellanova (and will be a world wide entity), while the cereal group will remain known as WK Kellogg Company. Interestingly, the Kellogg logo will be pronounced on both sets of company products (both the cursive font K, among other identifiers).
What kind of stuff will these new ventures be offering? Noodles, plant-based foods, snacks, and some frozen breakfast items. The brand names to be included are found in the chart below.
This could prove very interesting and provide us some lessons for our firms.
I wasn’t able to see the chart (used two different browsers). I loved Kellogg’s corn flakes as a child. I still enjoy breakfast cereal once a week (sometimes, more). I don’t think I’ll have much interest in Kellanova snacks, but yes, it will be interesting to see how both companies fare.
We’ll have to see how this turns out, Alana.
