"The freedom of the press may be affected by economic restrictions, both governmental and private, including action in support of the press — In this survey of press systems throughout the world (various countries and various political systems) the author particularly examines the practice of economic intervention and the controls exerted on the press in the non-democratic countries — These are the various points dealt with by the author — Private enterprise — The dangers of the concentration of property — Dangers of state intervention — Communist economic control — Thus the author examines the system of the press in relation to the type of power and to the economic situation of the country."
