Globalisation refers to the increasing integration and interdependence of world economies, cultures, and populations due to advances in transportation and communication. It involves the increased flow of trade, finance, culture, ideas, and people between countries. Key factors driving globalisation include reductions in transportation and communication costs, increased cross-border trade, and the growth of multinational corporations operating on an international scale. While globalisation has increased economic opportunities, it also poses challenges including job losses and threats to local cultures from the spread of popular global brands and media.
