Introducing Web 2.0

Web 2.0, a phrase coined by O'Reilly Media in 2004, refers to the second-generation of Web based communities and hosted services - such as social networking sites, wikis and folksonomies - that facilitate collaboration and sharing between users. O'Reilly Media titled a series of conferences around the phrase, and it has since become widely adopted.

Technologies such as weblogs, social bookmarking, wikis, podcasts, RSS feeds, social software, Web APIs, Web standards and online Web services have led to a significant shift in the way people use the web, characterized by:

  • The transition of Web sites from isolated information silos to sources of content and functionality, thus becoming computing platforms serving web applications to end-users
  • A social phenomenon embracing an approach to generating and distributing Web content itself, characterized by open communication, decentralization of authority, freedom to share and re-use, and "the market as a conversation"
  • Enhanced organization and categorization of content, emphasizing deep linking
  • A rise in the economic value of the Web, possibly surpassing the impact of the dot-com boom of the late 1990s
