The first documented photo upload initiative was Wikipedia Takes Manhattan, which took place on April 4, 2008, in New York. The event was coordinated by Wikimedia New York City, Columbia University, and New York University. The event focused around a scavenger hunt, in which participants would photograph subjects which the coordinating Wikipedia articles about those subjects were lacking images of the to-be photographed subject. Images were uploaded to Wikimedia Commons and used to illustrated Wikipedia articles. From 2008 on, a number of volunteers is other countries picked up the concept of organizing photo upload events that cover specific topics, in most cases within a local context.
