English became the predominant language of business during the second half of the Twentieth Century for various reasons. The USA became the world’s most important economic power and was also one of the ‘victors’, alongside Britain, of the Second World War. The increasingly international nature of business made moving towards a ‘common’ language a necessity. English was a perfect candidate as it was already spoken as a first or second language by many people around the globe (partially as a result of British colonialism). It is now spoken by over 500 million people in a vast number of territories, including Britain, Canada, the United States of America, Australia, India and Southern Africa and has truly become a ‘global’ language. Business English is therefore considered as being essential for all people who wish to work in any area of business, aviation, computing, etc. As the economy becomes increasingly global, the importance of Business English continues to grow.
