Contagious: Why Things Catch On

"Why do some ideas seemingly spread overnight, while others disappear? How can some products become ubiquitous, while others never gain traction? Jonah Berger knows the answers, and, with Contagious, now we do, too."

-CHARLES DUHIGG, author of THE POWER OF HABIT

"If you are seeking a bigger impact, especially with a smaller budget, you need this book. Contagious will show you how to make your product spread like crazy."

-CHIP HEATH, coauthor of MADE TO STICK and DECISIVE

"Jonah Berger is as creative and thoughtful as he is spunky and playful. Looking at his research, much like studying a masterpiece in a museum, provides the observer with new insights about life and also makes one aware of the creator's ingenuity and creativity. It is hard to come up with a better example of using social science to illuminate the ordinary and extraordinary in our daily lives."

- DAN ARIELY, author of PREDICTABLY IRRATIONAL

"Jonah Berger is the rare sort who has studied the facts, parsed them from the fiction-and performed groundbreaking experiments that have changed the way the experts think. If there's one book you're going to read this year on how ideas spread, it's this one."

• DAVE BALTER, co-founder of the Word of Mouth Marketing Association
