"Written for a wide audience, from undergraduate and graduate students to citizens and activists, this book will teach you about how economics has influenced the digital technologies that we use every day. Most media textbooks won't tell you much about economic terms, concepts or principles; this book will explain to you the economic theory and history underpinning everything from advertising to computers, social networking sites and streaming services. With examples ranging from Elon Musk's takeover of Twitter to Amazon and the world of online shopping, Caraway offers a personal perspective about today's media technologies that will enrich your understanding of their technical, cultural, and social significance."--Back cover.
