Why do some ideas catch fire while others disappear almost as soon as they arrive? Why does one video get shared by millions, one restaurant become the place everyone talks about, or one product suddenly feel like it is everywhere? At first glance, it can seem like luck. It can seem random, almost magical. But the big promise of this book is that word of mouth and social transmission are not mysteries. They follow patterns. They can be understood. And once you understand them, you can make your own messages, products, and stories far more likely to spread. That is the heart of Contagious.
