Contagious: Why Things Catch On

In "Contagious: Why Things Catch On," Jonah Berger, a marketing professor at the Wharton School, delves into the science behind why certain products, ideas, and behaviors become popular and spread like wildfire. Challenging the conventional wisdom that virality is a stroke of luck, Berger meticulously unpacks the six key principles that drive social transmission, encapsulated in his memorable acronym, STEPPS: Social Currency, Triggers, Emotion, Public, Practical Value, and Stories. Through a wealth of captivating case studies and scientific research, he illustrates how these often-overlooked factors influence word-of-mouth marketing, making it exponentially more effective than traditional advertising. This book offers a practical, actionable framework for anyone looking to create messages and products that are inherently shareable, ensuring their ideas don't just get noticed, but truly catch on and resonate with a broader audience.
