Since the late 1990s access to information and communication technologies (ICTs) has seen tremendous growth-driven primarily by the wireless technologies and liberalization of telecommunications markets. Mobile communications have evolved from simple voice and text services to diversified innovative applications and mobile broadband Internet. In 2016, there were more than 7.3 billion mobile-cellular subscriptions worldwide. Globally, 3.5 billion people were using the Internet, of which 2.5 billion were from developing countries. Mobile-broadband subscriptions have risen constantly to reach 3.6 billion, while the number of fixed-broadband subscriptions reached more than 884 million during the same period. The impacts of ICTs cross all sectors. Research has shown that investment in information and communication technoslogies is associated with sucheconomic benefits as higher productivity, lower costs, new economic opportunities, job creation, innovation, and increased trade. ICTS also help provide better services in health and education, and strengthen social cohesion.
