Celebrity advocacy has become an important part of the way in which development non-governmental organizations (NGOs), and charities more generally, try to achieve social and political change. Yet research into how different audiences respond to such advocacy is parlous. This article presents findings from two large surveys (1111 and 1999), focus groups (9) and interviews across the charitable sector and celebrity industries to explore those responses. These data suggest that celebrity advocacy is not a particularly popular phenomenon, but it is widely believed to be so. Celebrity advocacy is thus firmly entrenched in post-democratic politics and part of the public alienation from politics that term describes. Nevertheless, because celebrity advocacy also works well with political and business elites it may still be a good vehicle for pursuing some of the goals of development advocates.
