9 Trix Rabbit - 1960

Believe it or not, it was a stick-figure boy rather than a slender white rabbit that initially graced boxes of Trix cereal. In fact, the well-known hare didn't appear on the cereal's packaging until 1960, six years later. An advertising executive named Joe Harris came up with both the rabbit and the slogan, "Silly Rabbit, Trix are for kids," in August of 1959.
