This document summarizes the evolution of international business from the late 19th century to present day. It describes how globalization first began in the 1870s driven by industrialization, but was set back by World Wars. After World War 2, organizations like the IMF, World Bank, and GATT/WTO promoted global trade and reduced barriers. This led to a shift from simple exporting/importing to international marketing and production across borders by multinational companies. The scope and scale of international business has rapidly expanded in recent decades.
