The tipping point is that magic moment when an idea, trend, or social behavior crosses a threshold, tips, and spreads like wildfire. Just as a single sick person can start an epidemic of the flu, so too can a small but precisely target push a fashion trend, the popularity of a new product, or a drop in the crime rate. This widely acclaimed best-seller, in which Malcom Gladwell explores and brilliantly illuminiates the tipping point phenomenon, is already changing the way people throughout the world think about selling products and disseminating ideas.
