This chapter presents an overview of the book 'Platforms, Markets and Innovation' and summarizes each of its 14 chapters of cutting-edge research on technological platforms. Industry platforms such as Google or Microsoft Windows, embedded in industrial ecosystems, have redesigned our industrial landscapes, upset the balance of power between firms, fostered innovation and raised new questions on competition and innovation. Annabelle Gawer presents cutting-edge contributions from 24 top international scholars from the disciplines of strategy, economics, innovation, and organizations studies. The book offers a step towards an empirically based, nuanced udnerstanding of the nature of platforms and the implications they hold for the evolution of industrial innovation. With a multidisciplinary approach, this book will strongly appeal to academics and advanced students in management, innovation, strategy, economics and design.
