If you have kids - you probably took them to see Disney's High School Musical 3 last night...And if you have kids - they probably will put JibJab's new HSM3 widget on their MySpace pages.
This is what viral marketing should aspire to be: - customizable - engaging - fun and re-watchable
... and it clearly has a business model behind it! Furthermore - the branded experience is what makes the widget enjoyable and attractive. I have shown this to several people now and the reactions are instant laughter... followed by a rush to create their own video!
Well done JibJab!
