Fresh out of business school, Phil Knight borrowed $50 from his father and created a company with a simple mission: import high-quality, low-cost athletic shoes from Japan. Selling the shoes from the boot of his Plymouth, Knight grossed $8000 in his first year. Today, Nike's annual sales top $30 billion. In an age of start-ups, Nike is the one plus ultra of all start-ups, and the swoosh has become a revolutionary, globe-spanning icon, one of the most ubiquitous and recognisable symbols in the world today. But Knight, the man behind the swoosh, has always remained a mystery. Now, for the first time, he tells his story.
