| Abstract: | This article examines the mechanism underlying text production, using the framework set up by Prague School Linguists. It seeks to answer a fundamental question: 'how is a text built?', 'what do writers do to get the individual sentences of their texts to hang together and form a unified whole?' The discourse genre chosen to illustrate the study is news reporting, specifically the spoken media news. The data collected consist of two news issues broadcast over the Cameroon Radio and Television (CRTV): one is a radio news issue and the other, its televised counterpart. The analysis reveals that there are a total of 270 utterance themes in the two news issues, and three patterns of thematic progression (TP) are used: TP with derived themes, TP with a constant theme and the simple linear TP. It also reveals that the news discourse (be it on the radio or television) is characterized by a high proportion of thematic progression with derived themes, which tends to be used twice as frequently as the TP with a constant theme or the simple linear TP.
