The ONLY place Kashi acknowledges they are a Kellogg’s property is in the investor relations materials – never on the cereal boxes.
Kudos to Kellogg’s for recognizing that their shareholders like the Kellogg’s/Kashi financial brand story – but the healthy earthy crunchy folks who EAT Kashi cereal (and associate Kellogg’s brand with sicky-sweet-unhealthy cereal) do not. This was a very savvy and brand-humble decision by Kellogg’s marketing.
Not every “product” you may own fits under your brand, especially if you are active in M&A. Some can be assimilated overtime, but be wary if the house brand it so concrete in a wrong direction.
