'With a combination of acute observation, close analysis and clear-headed honesty, Rebecca Giblin leads the reader to share her conclusion that there is no legislative, judicial, commercial or technical panacea for copyright infringement which P2P software facilitates, but that even now it is not too late to improve the manner in which the rights-owning and distribution sectors address the challenges that P2P poses.' Jeremy Phillips, Olswang, and Intellectual Property Institute, UK Code Wars recounts the legal and technological history of the first decade of the P2P file sharing era, focusing on the innovative and anarchic ways in which P2P technologies evolved in response to decisions reached by courts with regard to their predecessors. With reference to US, UK, Canadian and Australian secondary liability regimes, this insightful book develops a compelling new theory to explain why a decade of ostensibly successful litigation failed to reduce the number, variety or availability of P2P file sharing applications and highlights ways the law might need to change if it is to have any meaningful effect in future. A genuine interdisciplinary study, spanning both the law and information technology fields, this book will appeal to intellectual property and technology academics and researchers internationally. Historians and sociologists studying this fascinating period, as well as undergraduate and graduate students who are working on research projects in related fields, will also find this book a stimulating read.
