A friend sent me this story about how 3 people in their 20s were able to create buzz, spread their message and raise thousands of dollars for a good cause. How? They utilized kids, duuh. As simple as it sounds, they knew their audience.
What started as a documentary about war-ravaged Northern Uganda and the suffering children face ended up being spread across the Internet, downloaded to iPods and covered by CNN. The name of their project is Invisible Children.
This is a great example of how to create a story, make people care about it and get them involved. If your product is interesting/unique/beneficial enough and you can tap into all the right channels-- especially, people themselves, the Internet, music, videos, iPods, TV etc.--then there's no telling how big and influential it can become.
