The first hackathon was held in 1999, and had 10 developers. Nowadays, hackathons like TechCrunch Disrupt and PennApps draw over 1000 hackers. There are hackathons happening almost every day, in cities all over the world. The themes of these hackathons range from music, television, mobile development, security, civic hacking, education, tourism, and almost anything you can think of.
Gracenote has been participating in hackathons all over the world. This presentation talks about the growth of hackathons, and the involvement of our developer program and API evangelists. It was presented at The State of Music Discovery event in Tokyo, Japan, on Feb 18th, 2014 (http://www.gracenote.com/events/musicdiscovery_japan2014), on the week of the first Music Hack Day in Tokyo.
