To achieve this, PMC uses long-running serialized melodramas written and produced in participating countries by local people in local languages. Characters are created that gradually evolve into positive role models for the audience. The emotional bonds that the audience forms with the characters and stories help inspire audiences to make positive changes in their lives. PMC's serial dramas have addressed issues such as: the use of family planning, reproductive health, avoidance of AIDS, elevation of women's status, protection of children, and related social and health goals, depending upon the relevance of each to the policies of the country in which PMC is working. PMC has now worked in 27 countries. Scientific research has shown that PMC's programs lead to population-wide behavior change.
