The main impact of communication technology has been on society. Let us look at two major impacts it has had.
First, communication technology has contributed greatly to globalization. As international telephone calls and, particularly, the internet have become cheaper and more readily available, companies in different countries can work together much more easily. This has helped to drive the globalization of the economy.
Second, communication technology has changed everyday life. People are more connected to one another via cell phones, Twitter, and other such technology. At the same time, it has created conditions in which people (in some jobs, at least) are never really separated from their work. The technology means that they are never really free because work can reach them at any time or place.
