The aim of this project was to develop a viral campaign concept to trigger other students to become a Player (member) of Play it Forward. Play it Forward’s (Pifworld) primary objective is to be the trusted and independent online platform for good causes, connecting people and non-profit organizations worldwide. The online platform is transparent, open en offers a unique way for institutions and individuals to support good causes. The concept and its manifestation in the Pifworld platform are in itself viral by nature: it’s a social network. To further stimulate the viral spread of PiF, we MediaLAB students will set up an online viral campaign to expand the amount of ambassadors and players in Pifworld. The goal is to have 10.000 Player registrations and a similar number of donations.
