"The study attempts a periodisation of the evolution of TfD and the development communication process in Africa. The perspective adopted spans within the larger scope of its implications and imperatives, to explore how this noble initiative that was given impetus by both Freire and Boal has developed in the continent over the years. This analysis is, therefore, undertaken from the following tripodal angles: I. The Pre-independence Era, II. The Post-independence Era, and III. The Electronic Culture Era. Conscious effort has been made to highlight the significant way in which patterns in social change within these epochs have particularly shaped the varying evolution trends." (Introduction)
