English and Business

English may be the language of business today but many know that there are no guarantees it will remain the language of business tomorrow. In fact, more business was conducted among nations (per capita) prior to World War I, when there was no uniform business language, than around the late 1990s, at the height of the .com boom and when English was the lingua franca of business.
