In this paper, I adopt a diachronic approach to the analysis of the two large SiBol newspaper corpora, in order to examine and compare the expression of evidentiality ( Bednarek, 2006 ; Dendale and Tasmowski, 2001 ; and Chafe, 1986 ) – that is, how the writer's knowledge is marked as having been ‘seen’ or ‘heard’, etc., how the knowledge is attributed, and how it is passed on to the reader. Findings show an increased use of evidential markers over the thirteen-year period studied, and, at the same time, a shift in reporter usage of evidentiality towards hearsay evidence and the reporting of knowledge acquired by speculation. This is in keeping with other observations regarding an increased ‘vagueness’ in contemporary journalism (see Duguid, 2010 ), which is counterbalanced at times with an elevation of the newsworker's presence.
