"The work is divided into two main parts: the effects of persuasion in communication; the effects of the specific types of media — The first part concentrates on the effects of strengthening opinions, forming new ones and changing attitudes by communications of the 'persuasive type, as well as the problem of the media and their audience — The second part studies in particular the effects of dealing with crime and violence in the various media, the effects of escapism, the exposing of children to TV and the passivity of the audience." (Jean-Marie Van Bol, Abdelfattah Fakhfakh: The use of mass media in the developing countries. Brussels: CIDESA, 1971 Nr. 1212, topic code 011, 020)
