if asked what is the most obvious sign of globalisation, most would say its either the dominance of Starbucks, or how Microsoft has invaded into most homes and offices around the world.
However, way before this, there was the spreading of religion around the world. from Chistianity, budhism, islam, hinduism and so many others. this exchange of idea took place way before starbucks set up it's first outlet of even when Bill Gates was still a child. infact, it is still happening around the world. people are preaching about their beliefs.
though it was a very slow process with the level of technology at that time, it is truly a sign of globalisation. the message did not travel electronically but by land, on the back of camels or horses.
