Non-fiction transmedia draws on the same definitions as fiction transmedia (PGA, 2010), which accepts without dispute the reference to ‘fictional story worlds’ (Jenkins, 2007; O'Flynn, 2012). By drawing attention to this grammatical oversight, we will review non-fiction transmedia literature, highlight the success of Go Back to Where You Came From (O’Mahoney, Australia, 2011) and provide a detailed analysis of the production of the The Living History of Fort Scratchley project (DVD documentary, i-doc, website, booklet, 2004–2008) against Henry Jenkins’ seven transmedia principles (2009b). This detailed analysis applies transmedia ‘fiction’ criteria to ‘non-fiction’, challenging transmedia’s explicit reference to fictional story universes.
