Pet Rock
The "Pet Rock" is a novelty item that became popular in the 1970s. Created by advertising executive Gary Dahl in 1975, it consists of a smooth rock sold in a cardboard box with air holes. The concept was to provide a low-maintenance pet that required no feeding, grooming, or walking.
The Pet Rock was marketed as a fun and humorous gift, appealing to people looking for a quirky present. It quickly gained popularity, selling millions of units within a short time. The phenomenon is often cited as an example of successful marketing and the power of simplicity in product design.
