Multinational corporations (MNCs) are companies that operate in multiple countries. They originated in the early 20th century and expanded greatly after World War II. MNCs have subsidiaries and operations in foreign countries, exercising control over policies across borders. While MNCs bring investment, jobs, and technology to host countries, they also face criticisms like manipulating markets and prioritizing home country interests. As India's economy grows rapidly, it attracts many MNCs in sectors like oil, infrastructure, and technology due to its large population and market. However, Indian MNCs expanding abroad face challenges in overcoming cultural and business differences.
