The document discusses using social videos to promote social causes. It finds that sharing social good videos is driven by feelings of happiness, warmth, and inspiration in viewers. Videos with highly emotional content, like those showing sadness or shock, tend to have lower sharing rates. The peak period for a video's sharing is within the first three weeks of its release, so launching a video widely maximizes sharing. Case studies show how low-budget, engaging videos on topics like helping a kitten can achieve millions of views and hundreds of thousands of shares.
