In 2004, a Chennai based entertainment-education non-governmental organization (NGO), Nalamdana, entered into collaboration with GHTM to supplement the education and counseling of patients in order to improve medication adherence.  Nalamdana would perform role plays about HIV transmission and medication in the outpatient area, involving patients and providers and also put on longer dramas staged at the GHTM auditorium for inpatient populations on similar issues. Through interactive feedback from providers and patients, Nalamdana in 2005 launched Thendral , a cable radio program reaching 7 of the 8 ART wards for two hours a day, six days a week (increased to four hours in 2007). 

The main aim of the study was to examine the relationship between exposure to Nalamdana programming (radio, role-plays, and dramas) and HIV/AIDS related behavioral outcomes
