This book investigates how the concentration of power among a small number of digital platforms impacts democratic processes, market competition, and public discourse. The authors, Martin Moore and Damian Tambini, draw upon their expertise in media policy and political communication to analyze the systemic influence of global tech giants. They present a framework for understanding the intersection of algorithmic control, data accumulation, and the erosion of traditional regulatory oversight in the digital age.

Experts in media policy and technology regulation frequently cite this work as a critical examination of the challenges posed by platform monopolies. Readers often note the academic rigor of the analysis, making it a standard reference for those studying the intersection of digital technology and governance.
