The document discusses the history and nature of narratives. It notes that the material medium used to convey narratives has changed over time from oral to written to digital. Each medium comes with unique attributes that influence how narratives are structured and experienced. The digital age in particular has coincided with new conceptions of narratives as nonlinear and multivariant due to the interactive capabilities of digital technologies. However, the author argues that for narratives to remain coherent, protocols are still needed to maintain a linear structure at the cognitive level.
