The nature, development and contribution of social marketing to public health practice since 2004 in England.

Social marketing is a highly systematic approach to health improvement that sets out unambiguous success criteria focused on behaviour change. This paper reviews the key concepts and principles of social marketing and its recent rapid development across government in England in the public health field. This paper outlines the role of the National Social Marketing Centre and concludes with a discussion of the probable future impact of social marketing on public health practice. The paper argues that there is a close ideological match between social marketing and liberal democratic imperatives. Social marketing's focus on outcome, return on investment and its emphasis on developing interventions that can respond to diverse needs, means it is probable that social marketing will increasingly be required by governments as a standard part of public health programmes.
