Abstract
In 1975, the Pet Rock was born. The egg-shaped, smooth stone came nestled in hay, accompanied by an instruction manual, and encased within a small cardboard box (see Figure 11-1). For $3.95, you could own one too. Although the Pet Rock started as a joke, it demonstrates why some products succeed and others fail.
