Boasting trillion-dollar companies, the digital economy profits from our emotions, our relationships with each other, and the ways we interact with the world. In this timely book, Tim Jordan deftly explores the workings of the digital economy. He discusses the hype and significance surrounding its activities and practices in order to outline important concepts, theory, and policy questions. Through a variety of in-depth case studies, he examines the areas of search, social media, service providers, free economic activity, and digital gaming. Companies discussed include Google, Baidu, Uber, Bitcoin, Wikipedia, Fortnight, and World of Warcraft. Jordan argues that the digital economy is not concerned primarily with selling products, but relies instead on creating communities that can be read by software and algorithms. Profit is then extracted through targeted advertising, subscriptions, misleading 'purchases', and service relations. The Digital Economy is an important reference for students and scholars getting to grips with this enormous contemporary phenomenon.
