Final answer:
The distribution of U.S. movies and television programs globally has prompted media globalization and Americanization, resulting in both cultural influence and protective measures by other countries.
Step-by-step explanation:
The distribution of U.S. movies and televisions programs throughout the world has led to media globalization, which is characterized by the worldwide integration of media through the cross-cultural exchange of ideas. This phenomenon has had significant cultural impact, leading to fears of the loss of unique cultural characteristics and the weakening of domestic industries in various countries. In response, nations like Brazil, Greece, Spain, South Korea, and others have taken measures such as imposing screen quotas to protect their local cultures and industries. Conversely, this spread of American culture, also known as Americanization, has facilitated the global dominance of American products and ideals, influencing local traditions and consumer choices while prompting some mixed reactions globally.
