Introduction

1. The Tipping Point is that magic moment when an idea, trend or social behavior crosses a threshold, tips, and spreads like wildfire. At what point does it become obvious that something has reached a boiling point and is about to tip?

2. The possibility of sudden change is at the center of the idea of the Tipping Point -- big changes occurring as a result of small events. If we agree that we are all, at heart, gradualists, our expectations set by the steady passage of time, is it reassuring to think that we can predict radical change by pinning their tipping points? Can we really ensure that the unexpected becomes the expected?
