A Multinational Corporation (MNC) is a large company that operates in multiple countries around the world. These corporations manage production or deliver services in more than one country, allowing them to reach a broader market. For example, a company like Coca-Cola sells its beverages globally, adapting its products to meet local tastes and preferences. MNCs often have a significant impact on the economies of the countries they operate in. They create jobs, invest in local communities, and contribute to economic growth. However, they can also face criticism for their influence on local cultures and economies, as seen with companies like McDonald's and their global presence.
