Information and communications technologies (ICTs) constitute a potentially transformative force in world politics. The industries associated with these technologies are growing rapidly, and some have argued that their importance in the overall economy at both the national and global levels increased in recent decades. ICT industries include both goods producers and service providers. ICT manufacturing includes all the goods-producing industries that use semiconductor components, such as consumer electronics, the computer industry, the telecommunications equipment industry, and industrial and military electronics. Within each of these groups, there are sub-industries that specialize in particular segments of the market. The services side of ICTs is also very large in terms of revenues and employment, and is growing rapidly. ICT services include, among others, the software industry, telecommunications services, data processing, and web-based information services. Many scholars argue that the importance of ICT industries goes beyond the revenues and employment generated in the industries themselves, however. ICTs may also be transformative in that they reduce transaction and communications costs in the overall economy. They make possible new forms of organization of human activity, especially as globalization and digitalization is progressing rapidly in the recent decades. Such processes have attracted the attention of international relations scholars, as they have been focusing on international regimes governing ICT-related activities in the past decade.
