Brands started out as communication tools to influence the image of companies or products (inside-out thinking) but have developed into channels of social forces. Powerful brands impact not just customer decisions but also markets and social institutions, such as fashion trends, city life, or even social movements. This book explores the implications of Niklas Luhmann’s theory of social systems for the theory and practice of agile brand management, in particular highlighting the central role of brand aesthetics and of brands as channels for mutual education between companies and consumers.
