The 2009 DARPA Network Challenge was a prize competition for exploring the roles the Internet and social networking play in the real-time communications, wide-area collaborations, and practical actions required to solve broad-scope, time-critical problems. The competition was sponsored by the Defense Advanced Research Projects Agency (DARPA), a research organization of the United States Department of Defense. The challenge was designed to help the military generate ideas for operating under a range of circumstances, such as natural disasters.[1] Congress authorized DARPA to award cash prizes to further DARPA's mission to sponsor revolutionary, high-payoff research that bridges the gap between fundamental discoveries and their use for national security.
In the competition, teams had to locate ten red balloons placed around the United States and then report their findings to DARPA. Due to the distributed nature of the contest, many teams used online resources, such as social media sites, to gather information or to recruit people that would look for balloons. Teams often had to deal with false submissions, and so they needed to come up with ways to validate and confirm reported sightings. The contest was concluded in under nine hours, much less than expected by DARPA, and had many implications with regards to the power of online social networking and crowdsourcing in general.[2]
In addition to the Network Challenge, DARPA has also conducted prize competitions in other areas of technology.
