Network Effect
Definition
The phenomenon where a product or service gains additional value as more people use it.
Deep Dive
The network effect is a powerful economic phenomenon where the value of a product or service increases for both new and existing users as more people adopt or use it. This growth in value is not linear but often exponential, creating a self-reinforcing loop that can lead to rapid adoption and market dominance. A classic example is a telephone network; its value is zero if only one person owns a phone, but it becomes immensely valuable as more people acquire phones and connect to the network. This effect can be direct, where the value comes from direct interaction with other users, or indirect, where the value comes from complementary goods or services that grow with the user base.
