We see influences of our culture in nearly every corner of the globe, impacting countless societies. Is there any country that doesn't have a McDonald's on every corner? And who hasn't tasted Coca-Cola at least once in their lives? These are just 2 of the countless examples as to why the American culture is imperialistic- one can't escape it! Since the early 20th century, the United States has been making and distributing films, with our ideas and culture embedded throughout every one. As these films were seen in other countries, many containing strong pro-American messages, the American way of life became very desireable to people in other countries. Suddenly, our culture was seen as the norm, and was being adopted by more and more people each day, who were striving to be like the protagonist of their favorite film. Movies are just one of the media sources that perpetuate this idea of cultural imperialism, and they are (and continue to be) a major factor in globalization as well.
