For decades, Nikes campaigns have been so radically creative that they make an indelible mark on the public imagination - and, just sometimes, change how the world thinks. Its an art form that Greg Hoffman understands better than anyone. Over 30 years at Nike, he crafted some of the most iconic campaigns in history: from Colin Kaepernick's Dream Crazy ad, to the instantly recognisable logos used by Roger Federer and Serena Williams. By the end of his career, he was Chief Marketing Officer - responsible for maintaining the brand recognition of the Nike swoosh everywhere on Earth. Now, Hoffman reveals the simple principle that Nike use to power their creativity: emotion by design. Combining scientific analysis and artistic daring, emotion by design helps Nike forge deep, personal bonds with their customers - crafting campaigns that chime with people's most audacious dreams.
