"The problem of jamming in international broadcasting — The start of jamming — Development — The Cold War and "jamming" — Anti-jamming techniques — Cooperation and understanding between peoples should be the primary aim: jamming should disappear after an agreement made under United Nations' supervision in order that all programmes may be broadcast in their entirety and heard without interruption." (Jean-Marie Van Bol, Abdelfattah Fakhfakh: The use of mass media in the developing countries. Brussels: CIDESA, 1971 Nr. 308, topic code 29)
