Information obtained in a survey of the uses of radio and television in connection with literacy work in 40 countries of the world is presented. Much of the information consists of replies to Unesco questionnaires on the subject. The countries surveyed were: Algeria, Cameroon, Central African Republic, Chad, Congo (Brazzaville), Ethiopia, Gabon, Guinea, Ivory Coast, Kenya, Madagascar, Mali, Niger, Rwanda, Senegal, Sudan, Tunisia, United Arab Republic, Upper Volta, Zambia, Cuba, Guatemala, Jamaica, Mexico, United States, Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, Burma, China (Republic of--Taiwan), India, Iran, Laos, Italy, Spain, and Yugoslavia. A profile or composite picture of practices and experience in various countries is presented. The survey showed that broadcasting is making a valuable and in some cases essential contribution to literacy campaigns. Recommendations made include the following: (1) All the various ways of using radio and television should be fully exploited in all countries that have a sizeable illiteracy problem; (2) This should be done as part of an overall plan to develop the new techniques of communication for economic and social, and especially educational, advancement; (3) Research that aids in planning and further research as well as into "methods" and "materials" is needed; and (4) Training centers and programs for broadcasting personnel are needed.
