Worldwide, over 33 million people are living with HIV/AIDS. It is estimated that over a third of those infected do not know their HIV status. Over half of the new HIV infections worldwide are in young people under the age of 25 (UNAIDS/WHO). Worldwide, over 3.9 billion people have mobile phones. In the Global AIDS Personal Public Service Announcement Project (GAPPSA), ten student teams on six continents will use cell phones to fight AIDS. In one day (4/22/10), student teams using only cell phones and laptop computers will plan, script, shoot, edit and premiere video messages encouraging their friends to be tested for HIV. Through the GAPPSA young people will use their most cherished technology to live longer, healthier lives. This paper will discuss this project and will explore the potential for new mobile media technologies to have a positive impact on people lives.
