I've been involved with helping launch multi-platform stories for several decades, you know, what folks are now calling 'transmedia.' On Monday I spent a few hours in a room filled with Ph.D. students in Santa Barbara, looking at the evolution of the form in a talk I call "Transmedia Sorting Hat," with a tip of the lid to one of the most successful commercial transmedia properties of all time. The slideshare upload embedded below includes my notes. Love to hear feedback.
