To help celebrate the 40 year anniversary of the Internet, the Defense Advanced Research Projects Agency (DARPA) set out to learn how quickly people could use online social networks to solve a problem. More than 4,000 teams participated in this national balloon hunt.
Effectively 10 balloons were deployed across the US and a 40,000 dollar prize went to the team who first identified all 10 locations correctly. That team was from MIT and was led by Riley Crane from MIT's Media Lab. Another example of the applied power of the social networks which were abuzz all over the weekend as the different teams applied different strategies to garner the location information.
