Effect of US popular culture has it been global?

Yes. Ask anyone from another country and you'll hear the same thing. Our popular culture is everywhere - from movies, to music, to books, to video games. Even the quintessential "American" style of dressing has spread all over the world. Blue jeans and t-shirts abound! In fact, our popular culture is so pervasive that some countries, like France for example, have passed laws that force radio stations to air music from their country to lessen the impact of American popular culture and keep their culture intact.
