Facebook F8 (pronounced "eff eight") is a mostly-annual conference held by Facebook, intended for developers and entrepreneurs who build products and services around the website. It is hosted in the San Francisco Bay Area, California, previously in San Francisco (until 2016) and now in San Jose, in Silicon Valley. Previous events have started with a keynote speech by Facebook founder Mark Zuckerberg, followed by various breakout sessions concentrating on specific topics. Facebook has often introduced new features, and made new announcements, at the conference. The "F8" name comes from Facebook's tradition of 8 hour hackathons. The scheduling of F8 has been somewhat erratic. No conferences were held in 2009, 2012 or 2013, and the date for the 2011 conference was announced late in the year.
