DMI runs evidence-based radio, television and mobile campaigns to change behaviours and save lives in developing countries.


Development Media International (DMI) produces radio and television programming in developing countries that encourage people to adopt improved health practices, such as exclusive breastfeeding of infants and seeking treatment for symptoms associated with fatal diseases. The program aims to reduce mortality among children less than five years old. Conceptually, mass media interventions have the potential to be highly cost-effective, though GiveWell has not seen strong evidence that they are cost-effective in practice.

Development Media International (DMI) is focused on producing and broadcasting radio, TV and mobile campaigns to change behaviours and save lives in developing countries. 


Child survival

DMI promotes health interventions that reduce child mortality, such as better nutrition and the treatment of diarrhoea, malaria and pneumonia, to improve parents' knowledge and behaviors. 

Family planning

DMI shares information on contraception, which saves mothers' and children's lives by avoiding high-risk pregnancies, but is only used by 22% of women in Africa (compared to 75% in developed countries). 

Early childhood development 

Parents can develop their children's cognitive abilities, simply by talking to them a great deal and in the right way. However, in many countries, few parents talk much to their children before they start talking, simply because it is not a social norm.

DMI's work


DMI designs and runs large-scale studies to generate evidence that mass media campaigns can change behaviours in developing countries.


It designs, run and evaluates media campaigns at scale, often in a single country but also in multiple countries through our 'DMI Reach' capability.  


It helps other organisations to design, run and evaluate media campaigns by providing them with bespoke advisory and consulting services.


DMI's approach


  • Broadcast several times per day in local languages
  • Work with stations with large audiences

DMI applies a basic but frequently forgotten principle of commercial marketing: saturation (reach and frequency). Media campaigns are only effective if they reach the majority of the target audience, even in remote areas, and reach them often enough to drive home the key messages and calls to action. 



  • Use modelling to estimate impact 
  • Allocate airtime based on impact
  • Measure and attribute impact robustly

Media campaigns will only be legitimate interventions if they show impact. Until recently there was little evidence that media campaigns change behaviours. DMI has run the first randomised controlled trial to prove that a media campaign changed health behaviours in a developing country.



  • Feed formative research into creatives
  • Use drama to tackle barriers to change
  • Test all materials before and afterwards

DMI believes that it needs to conduct research to understand the values, motivations and concerns of their target audience to change behaviors. Media campaigns should be simple, funny, and engaging, convincing people to change their behaviours, rather than simply providing information.

Proven track record

A few examples of DMI’s successful campaigns are:

  • Use of iron supplements among pregnant women increased from 10% to 44% in Cambodia
  • Trachoma incidence decreased from 72% to 52% in Ethiopia
  • Breastfeeding rates among new mothers increased from 77% to 91% in Orissa, India

Rigorous evaluations and transparency

DMI has unusually strong self-analysis – particularly in its support for a randomized-controlled trial (RCT) on its programme. It uses a model developed in conjunction with the London School of Hygiene, and a rigorous RCT funded by the Wellcome Trust and Planet Wheeler Foundation. DMI also shared significant, detailed information about its programme for GiveWell's evaluation process.



Economies of scale mean that DMI can educate communities about multiple health issues in a single campaign for little extra cost. Conceptually, mass media interventions have the potential to be highly cost-effective, though GiveWell has not yet seen strong evidence that they are cost-effective in practice. The Life You Can Save estimates that it costs only $20 per disability-adjusted life year (DALY), or $600 per life saved,* making it one of the cheapest health interventions available.
