In this day and age of globalisation, there are certain things that are more global than others. As I wrote in an analysis back in 2004, global are things that six different people of different nationalities and walks of life on a long distance flight can talk about.
Most things global, in 2004 and still today, are of course, Anglo-American. Courtesy of the language.
Movies such as When Harry Met Sally and You Got Mail, both with Meg Ryan, are part of global pop culture.
Paris is global too. The French language, not. Sorry M. Shirac!
To become part of global markets, pop culture and other dimensions of it, is not easy, of course. One either inherits it or works hard and smartly to achieve it.
Ancient Greece did.
