BarCamp is an international network of user-generated conferences primarily focused around technology and the web. They are open, participatory workshop-events, the content of which is provided by participants. The first BarCamps focused on early-stage web applications, and were related to open source technologies, social software, and open data formats. The format has also been used for a variety of other topics, including public transit, health care, education, and political organizing. The BarCamp format has also been adapted for specific industries like banking, education, real estate and social media. History The name BarCamp is a playful allusion to the event's origins, with reference to the programmer slang term, foobar: BarCamp arose as an open-to-the-public alternative to Foo Camp, which is an annual invitation-only participant-driven conference hosted by Tim O'Reilly. The first BarCamp was held in Palo Alto, California, from August 19–21, 2005, in the offices of Socialtext. It was organized in less than one week, from concept to event, with 200 attendees. Since then, BarCamps have been held in over 350 cities around the world, in North America, South America, Africa, Europe, the Middle East, Australasia and Asia. Attendees have often travelled internationally to attend BarCamps. To mark the first anniversary of BarCamp, BarCampEarth was held in multiple locations worldwide on August 25–27, 2006. The second anniversary of BarCamp, BarCampBlock, was held in Palo Alto at the original location, but also over a three block radius on August 18–19, 2007, and was attended by over 800 people. The largest recorded BarCamp took place in January 2013 with over 6400 confirmed registered attendees in Yangon, Myanmar (Burma). The January 2010 BarCamp Yangon attracted over 4700 attendees (confirmed with registration forms). Influence BarCamp makes their organizational process freely available, codifying it in a publicly available wiki. In addition to the BarCamp-branded network, it is also a model for user-generated conferences in other fields and for more specialized applications such as EdCamp, IndieWebCamp, WordCamp, crisis camps, and SkeptiCamp. Structure and participatory process Unlike traditional conference formats, both BarCamps and FooCamps have a self-organizing character, relying on the passion and the responsibility of the participants. Attendees schedule sessions by writing on a whiteboard or putting a Post-It note on a 'grid' of sessions. Those giving sessions are discouraged from using the sessions for promotion. BarCamps are often organized largely through the web; anyone can initiate a BarCamp using the BarCamp wiki. Although the format is
