I can’t speak for the rest of the world, but in Serbia 90% of TV shows and movies are American, and generally people watch primarily American movies/series online and in cinemas. Most people listen to American music and use English words in daily conversation. Most are familiar with things like 9/11, Vietnam, 4th of July, Woodstock, hippies etc.

A lot of younger people are more familiar with American history, topics, movies and music than their own culture. I’m not saying it’s good, but Americans have an undeniably strong cultural influence, at least in Europe.
