This book presents a transnational and transsystemic perspective on the role of contract in Internet Governance, and considers parameters for assessing the utility and legitimacy of contracts in this context. Bygrave presents definitions and parameters of internet governance and the role of contract alongside examples of how these are used in the ever-changing internet world. He examines topical and well-known mediums such as Facebook in relation to their policies and online parameters. Taking into account legal developments across jurisdictions and within both common law and civil law systems, Bygrave explores the idea of the contract as the principal means of governing the virtual world.
