Above, a 4-minute video of Joe Sabia talking about the evolving technology used to tell stories.
On a related note, take a look at this New Scientist article that lays out some fine examples of e-storytelling; also worth checking out is the more complete electronic literature collection from which it draws.
I'm relieved to report that neither the video presenter nor the article above make any extravagant claims about how new media are revolutionizing storytelling. Certainly, there are exciting new forms taking their place alongside the novel and the film and so on. An online story-game allows you to choose your own path, or an iPad app lets you get the back-story on the characters and places in a novel, or you can post a comment on a video story. To my mind, the impulses behind the supposedly "new" interactive storytelling -- the desire to get lost in or contribute to a story -- have not changed. And there are analogue counterparts to most of these new technologies. They have not -- yet -- fundamentally altered the nature of storytelling, which relies on imagination and conversation just as much as it ever did.
