What's going on with processed food crossover flavors?

Shopping in the grocery store lately, I keep seeing things like Dr Pepper flavored Peeps, Pringles Flavored Morningstar Chick'n Fries, Olipop flushable Goodwipes, Girl Scout Cookie shampoo, etc. What has changed in corporate branding etc that has led to this sudden proliferation of crossovers?
