Like Minds, Like Mine in New Zealand, a public health-funded project to reduce the stigma of mental illness and the discrimination that people with experience of mental illness face everyday in the community, has a video of one of its campaigns on YouTube. It appears to have made it onto to YouTube because it uses the catchy tune "You Gotta Be" by Desiree. Their anti-stigma message is being spread worldwide thanks to YouTube, and the viewers seem to like excellent ad.
Thanks to Ken for the tip.
