What makes things popular? And what makes online content go viral?
Why do people talk about certain products and ideas more than others? And Why are some stories and rumors more infectious?

Jonah Berger has spent the last decade answering these questions. He’s studied why New York Times articles make the paper’s own Most E-mailed list, why products get the buzz they do, and how social influence shapes everything from the cars we buy to the clothes we wear to the names we give our children. In this book, Berger combines ground-breaking research with powerful stories and reveals the secret science behind word-of-mouth and social communication. Contagious provides specific, actionable techniques for helping information spread—for designing messages, advertisements, and content that people will share. Whether you’re a manager at a big company, a small business owner trying to boost awareness, a politician running for office, or a health official trying to get the word out, Contagious will show you how to make your product or idea catch on.
