Globalization is the increasing interconnectedness between countries through international trade and cultural exchange. It has increased rapidly in the last 50 years as improvements in technology and transportation have lowered barriers to trade. Major companies have expanded internationally and become multinational corporations, and goods and services are increasingly produced on a global scale for international markets. Hollywood films in particular have found success globally, and now represent over half of box office receipts in many major international markets, showing the convergence of popular tastes internationally, though against a backdrop of some local cultural differences remaining.
