"There are differences between the various countries as regards the freedom of the national press and the levels of information given — While some countries enjoy complete freedom of the press, others have no experience of it — Certain countries are „swamped“ with information, others are largely „isolated“ from the outside world — The present study sets out to study and examine the question inorder to discover the major factors responsible for these differences." (Jean-Marie Van Bol, Abdelfattah Fakhfakh: The use of mass media in the developing countries. Brussels: CIDESA, 1971 Nr. 797, topic code 070, 04)
