Contagious: Why Things Catch On

Why do certain products and ideas go viral? Dynamic young Wharton professor Jonah Berger draws on his research to explain the six steps that make products or ideas contagious.

Why do some products get more word of mouth than others? Why does some online content go viral? Word of mouth makes products, ideas, and behaviors catch on. It’s more influential than advertising and far more effective.

Can you create word of mouth for your product or idea? According to Berger, you can. Whether you operate a neighborhood restaurant, a corporation with hundreds of employees, or are running for a local office for the first time, the steps that can help your product or idea become viral are the same.

Contagious is filled with fascinating information drawn from Berger’s research. You will be surprised to learn, for example, just how little word of mouth is generated online versus elsewhere. Already praised by Dan Ariely and Dan Gilbert, and sold in nine countries, this book is a must-read for people who want their projects and ideas to succeed.
