The purpose of this paper is to discuss what has made English a global language and outline the (positive and negative) effects of globalization on English language teaching (ELT). Nowadays, the world is enchanted with what new information technology has made possible to the point that the world has become digitally controlled. This digital revolution has spread throughout the world and into many private homes and businesses. What we call it globalization is a result of this information technology which I consider now the basic of our daily activities. This technology has affected other sides of our life and interacted with our cultures and traditions through moving and merging some habits, customs, cultures or values of different societies into each other to create the concept of globalization. Among the things that have been affected by globalization is ELT. That is, with the rapid pace of globalization, there has been a major change in the field of ELT.
