A Goodwill ambassador is an honorary title and often linked with non-profit related causes. Their primary function is to help non-profit organizations spread their message across. Predominantly, goodwill ambassadors are celebrity advocates or known personalities, who use their fame and talent to get funding, donations, encourage volunteers to participate and raise awareness towards the organization's cause. In the past many organizations such as UNESCO have endorsed their cause through UNESCO Goodwill Ambassador. These celebrities or known personalities are picked according to the organizations' intended audience and if fully invested in the cause they are promoting they can greatly influence the process of persuading others. Goodwill ambassadors make widely publicized visits to the world's most troubled regions, and make appeals on behalf of their people and the organization. For example, the United Nations Goodwill Ambassadors include famous celebrities like Angelina Jolie for UNHCR, David Beckham, Shakira for UNICEF, Christina Aguilera for WFP and Nicole Kidman for UN Women.
