Creative Ad

Public service advertising
The advertising techniques used to promote commercial goods and services can be used to inform, educate and motivate the public about non-commercial issues, such as HIV/AIDS, political ideology, energy conservation and deforestation.
Advertising, in its non-commercial guise, is a powerful educational tool capable of reaching and motivating large audiences. "Advertising justifies its existence when used in the public interest—it is much too powerful a tool to use solely for commercial purposes." Attributed to Howard Gossage by David Ogilvy.
