This program was developed at the Interactive Media Lab at Dartmouth as the result of a grant from the Robert Wood Johnson foundation in 2003. After 2010, once licensed to World 2 Systems, this program was updated to run on the web with via additional funding from Robert Wood Johnson and the Centers for Disease Control and Prevention.
It was primarily through generous funding from the CDC that the program remained in use until 2018. Unfortunately the technology that was used to create the program Adobe Flash was never usable on IOS and announced its end of life in 2017.
As a result of these and other financial issues the program was discontinued and is no longer in use.
