The Web 2.0 Summit (originally known as the Web 2.0 Conference) was an annual event, held in San Francisco, California from 2004 to 2011, that featured discussions about the World Wide Web. The event was started by Tim O'Reilly, who is also widely credited with popularizing the term "Web 2.0". It was organized by O'Reilly's company, O'Reilly Media, with O'Reilly and journalist/entrepreneur John Battelle serving as co-moderators. The Web 2.0 Summit was an invitation-only event and featured many of the most prominent entrepreneurs and thinkers of the web community.
Spin-off events included the Web 2.0 Expo, which lasted from 2007 to 2011,[1] and the Gov 2.0 Summit, which occurred in 2009 and 2010.
