Storytelling is a two way street
A quick thought about storytelling... Thought this ad was a nice example of storytelling and nifty animation to boot.

Here's a pretty cool look at how they made the ad:

Along these lines, I saw this interesting article in the Wall Street Journal about how "Carrying a bottle of Vegetable Juice Has Become a Status Symbol." The point the article makes which I hope circles back to this advert (see how I used the British term for a British ad) is that people buy things it sends a signal to the world about who they are, what they believe, what their values are. A $10 bottle of juice is crazy unless it "...convey[s] the impression of superior health and discipline."
See storytelling works both ways. A product a candidate has to tell a story to get folks to pay attention, but where things get interesting is when the audience adopts the brand because it tells their story too.
