The latest example of this strategy is Kellogg's Raisin Bran, one of the best selling cereals on the market. The Battle Creek company has been gradually adding new cereals to the Raisin Bran portfolio, including three quite recently: Crunch Apple Strawberry, Cranberry Almond Granola, and Raisin and Honey Granola. This now brings to seven the number of offerings with "two scoops of raisins" along with fiber-rich bran.
The new Crunch Apple Strawberry, in particular, looks real interesting, and something I definitely want to try. I suspect others will as well, and that is just the way Kellogg wants it.
