Contagious

Contagious examines what makes a product, idea or behavior more likely to be shared among many people. The book explores the question of whether contagious things are accidents or the results of good marketing, or whether contagiousness is an inherent feature of a product, idea or behavior. It argues that, far from being merely a matter of luck, the majority of very popular products and ideas are the result of a combination of savvy planning and execution.
