The twentieth century has witnessed a great number of fascinating and amazing changes among which, I believe, the internet technology is the one that should be remembered because it has created not only a rapid and affordable form of communication but also a valuable method for allowing better access to information. Generally speaking, the internet has improved communication in the twentieth century tremendously. The wide use of email is a good case in point, which is an excellent and efficient way to keep friends, coworkers or family members in touch. Before the existence of the internet and email, most people have to mail their letters through post office, which is slow and costly, especially when the cities are far apart in distance.
