In the context of a conference themed “After media,” this paper suggests a notion of after-media – not as a time beyond the demise of some particular media, but as an approach where the goals of a new medium are made explicit in relation to its historical foundations and practices. The author presents several principles and trajectories that shape his approach toward mobile after-media. These theoretical concerns are made more tangible by an explanation of the author’s project Datascape, a geographic storytelling platform that supports the telling of locative narratives by artists, researchers, educators and community groups.
