While the common perception is that the Internet is a chaotic, unregulated space over which States have no, or at best, limited control, the legal reality is very different. States across the globe have sought to impose their laws on online activity, including activity which originates from abroad. This book examines the legitimacy and effectiveness of these regulatory attempts, the cost of such regulation or its absence, and what, if anything, can and should be done to create a more legally ordered online environment.
