Everyday Example
WhatsApp is only useful if the people you want to message are on it. The more people join, the more valuable it becomes for everyone — a classic network effect.

Metcalfe's Law (1980) formalised network effects: the value of a network grows proportionally to the square of its number of users. A network of 10 users has 100 connection points; 100 users has 10,000.
