Discrimination in the food industry?

Why are there no female cartoon characters representing breakfast cereals? You have Cap N Crunch, Tony the Tiger, Snap, Crackle, Pop, Frankenberry, erry, Count Chockula, Toucan Sam, the Trix rabbit, Super sugar crisp bear, Cookie Jarvis(cookies for breakfast is a whole other issue), the Quaker Oats Quaker dude, Coocoo for Coco puffs, The sun on the Raisin Bran box is apparently male, and Corn Flakes uses a rooster. Does it have anything to do with male testosterone levels being highest in the morning?
