As Displayname posted, expanding portfolio with different brands increases sales without the fear of the main company dominating the market in perception. Food companies have been buying out the natural/organic brands to change image and increase sales without spending the initial build up and R&D. General Mills bought Cascadian Farms and Muir Glen. Kellogg's bough Kashi and Gardenburger, Coca Cola bought Honest Tea, Hansen's/BlueSky, and Zico Coconut Water. Hormel bought Applegate Farms. Seems large electronics companies are just doing the same as the food companies.
