Globalization is the increasing integration and interaction between people, companies, and governments of different nations, driven by international trade and investment and aided by information technology. It involves the movement of goods, services, capital, people, technology, and ideas across national borders. Key drivers of globalization include developments in transportation and communication technologies as well as the growth of transnational corporations that operate in multiple countries. While globalization has increased economic growth and cultural awareness, it has also widened income inequality and threatened some local cultures and environments.
