UNESCO is a specialised institution of the United Nations. Currently it has 185 Member states, up from 20 at its creation in 1946. It was created to monitor fundamental world changes and to help Member states find answers to the key questions of our societies in the areas of its competence. UNESCO has a wide range of activities. Thus the term science also covers tasks which fall within the social and human sciences, and even if its logo does not evoke communication, UNESCO plays an important role in areas as different as data exchange and the creation of infrastructures for communication .
