Facebook F8 (pronounced "eff eight") is a mostly-annual conference held by Facebook that is intended for developers and entrepreneurs who build products and services around the social network. The event started with a keynote speech by Facebook founder and CEO Mark Zuckerberg, followed by various breakout sessions concentrating on specific topics.
The name "F8" derives from the tradition at Facebook of having a big eight-hour Hackathon just after the event.
The first F8 event was held at the San Francisco Design Center in San Francisco. At this event, the social graph was introduced.
