Networking technologies such as peer-to-peer file-sharing and Web 2.0 are here to stay yet the conflicts between their users and copyright owners remain unresolved and copyright enforcement became increasingly difficult. This legal, economic and social analysis of networking technologies, focuses on the liabilities of users and intermediaries. The book analyses the numerous international strategies proposed and implemented to control or stop the phenomenon in order to determine the optimal method for compensating copyright owners without stifling innovation and undermining users' rights. The author concludes that the most effective way to achieve this difficult balance is through a collectively-managed and centrally-administered, remuneration right for user-initiated non-commercial dissemination of copyright protected materials.
