Here's a presentation I created for a local client that wants to use transmedia for the benefit of their clients. It's goal is to explain the power of transmedia in engaging consumers in a storyworld and how it's different to product placement and branded entertainment.
Specifically I use an ARG (alternative reality game) to illustrate how it can work with an integrated marketing communications plan.
I had to hold off making the document public but now it's out! I'd be interested to hear thoughts from anyone working in this area. Hope it doesn't horrify anyone :)
