The internet is a set of software instructions (known as “protocols”) capable of transmitting data over networks. These protocols were designed to facilitate the movement of data across independently managed networks and different physical media, and not to survive a nuclear war as the popular myth suggests. The use of the internet protocols gives rise to technical, legal, regulatory, and policy problems that become the main concern of internet governance. Because the internet is a key component of the infrastructure for a growing digital economy, internet governance has turned into an increasingly high-stakes arena for political activity. The world’s convergence on the internet protocols for computer communications, coupled with the proliferation of a variety of increasingly inexpensive digital devices that can be networked, has created a new set of geopolitical issues around information and communication technologies. These problems are intertwined with a broader set of public policy issues such as freedom of expression, privacy, transnational crime, the security of states and critical infrastructure, intellectual property, trade, and economic regulation. Political scientists and International Relations scholars have been slow to attack these problems, in part due to the difficulty of recognizing governance issues when they are embedded in a highly technological context. Internet governance is closely related to, and has evolved out of, debates over digital convergence, telecommunications policy, and media regulation.
