Final answer:
Global marketing occurs when a company operates in international markets beyond its home country, and is a key aspect of globalization, involving the integration of trade across national borders.
Step-by-step explanation:
Global marketing occurs when a company operates in markets in other countries beyond its home country. This is a hallmark of globalization, which is characterized by the trend of buying and selling in markets that increasingly cross national borders. Companies that engage in global marketing become part of the goods and services market, where firms are sellers of what they produce, and households are buyers. It's not just about operating in more than three countries or introducing a new product; it's about a strategic presence in multiple international markets.
Multinational corporations (MNCs) play a key role in globalization, often starting with market expansion motives that lead to a snowball effect of economic and cultural integration. Globalization has led to the integration of governments, cultures, and financial markets through international trade into a single world market, and MNCs that conduct their business across national borders become significant participants in the economies of the countries they operate in.
