  • As used by its proponents, the phrase "Web 2.0" refers to one or more of the following:

    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"
    A more organized and categorized content, with a far more developed deeplinking web architecture than hithertofore
    A shift in economic value of the Web, possibly surpassing that of the dot com boom of the late 1990s
    A marketing-term used to differentiate new web-based firms from those of the dot-com boom, which (due to the bust) subsequently appeared discredited
    The resurgence of excitement around the implications of innovative web-applications and services that gained a lot of momentum[citation needed] around mid-2005
  • Tim O'Reilly and John Battelle summarized key principles they believed characterized Web 2.0 applications:

    the Web as a platform
    data as the driving force
    network effects created by an architecture of participation
    innovation in assembly of systems and sites composed by pulling together features from distributed, independent developers (a kind of "open source" development)
    lightweight business models enabled by content and service syndication
    the end of the software adoption cycle ("the perpetual beta")
    software above the level of a single device, leveraging the power of The Long Tail.

  • Web 2.0, a phrase coined by O'Reilly Media in 2004,[1] refers to a perceived second-generation of Web-based services—such as social networking sites, wikis, communication tools, and folksonomies—that emphasize online collaboration and sharing among users. O'Reilly Media used the phrase as a title for a series of conferences, and it has since become widely adopted.


    Though the term suggests a new version of the Web, it does not refer to an update to Internet or World Wide Web technical standards, but to changes in the ways those standards are used. According to Tim O'Reilly, "Web 2.0 is the business revolution in the computer industry caused by the move to the internet as platform, and an attempt to understand the rules for success on that new platform."[2].


    Some technology experts, notably Tim Berners-Lee, have questioned whether the term is meaningful, since many of the technology components of "Web 2.0" have been present since the creation of the World Wide Web

    On September 30, 2005, Tim O'Reilly wrote a piece summarizing his view of Web 2.0. The mind-map pictured above (constructed by Markus Angermeier on November 11, 2005) sums up some of the memes of Web 2.0, with example-sites and services attached.

    In studying and/or promoting web-technology, the phrase Web 2.0 can refer to a perceived second generation of web-based communities and hosted services — such as social-networking sites, wikis, and folksonomies — which aim to facilitate creativity, collaboration, and sharing between users. The term gained currency following the first O'Reilly Media Web 2.0 conference in 2004.[2][3] Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but to changes in the ways software developers and end-users use webs. According to Tim O'Reilly,



    "Web 2.0 is the business revolution in the computer industry caused by the move to the Internet as platform, and an attempt to understand the rules for success on that new platform." [4]



    Some technology experts, notably Tim Berners-Lee, have questioned whether one can use the term in a meaningful way, since many of the technology components of "Web 2.0" have existed since the early days of the Web.[5][6]

  • t does not refer to an update to any technical specifications, but to changes in the ways software developers and end-users use the Web. According to Tim O'Reilly:
  • Web 2.0 has numerous definitions. Basically, the term encapsulates the idea of the proliferation of interconnectivity and interactivity of web-delivered content. Tim O'Reilly regards Web 2.0 as business embracing the web as a platform and using its strengths, for example global audiences.[3] O'Reilly considers that Eric Schmidt's abridged slogan, don't fight the Internet, encompasses the essence of Web 2.0 — building applications and services around the unique features of the Internet, as opposed to expecting the Internet to suit as a platform (effectively "fighting the Internet").

  • In the opening talk of a first Web 2.0 conference, O'Reilly and John Battelle summarized what they saw as the themes of Web 2.0. They argued that the web had become a platform, with software above the level of a single device, leveraging the power of the "Long Tail", and with data as a driving force. According to O'Reilly and Battelle, an architecture of participation where users can contribute website content creates network effects. Web 2.0 technologies tend to foster innovation in the assembly of systems and sites composed by pulling together features from distributed, independent developers. (This could be seen as a kind of "open source" or possible "Agile" development process, consistent with an end to the traditional software adoption cycle, typified by the so-called "perpetual beta".)


    Web 2.0 technology encourages lightweight business models enabled by syndication of content and of service and by ease of picking-up by early adopters.[7]


    O'Reilly provided examples of companies or products that embody these principles in his description of his four levels in the hierarchy of Web 2.0 sites:

    • Level-3 applications, the most "Web 2.0"-oriented, exist only on the Internet, deriving their effectiveness from the inter-human connections and from the network effects that Web 2.0 makes possible, and growing in effectiveness in proportion as people make more use of them. O'Reilly gave eBay, Craigslist, Wikipedia, del.icio.us, Skype, dodgeball, and AdSense as examples.

    • Level-2 applications can operate offline but gain advantages from going online. O'Reilly cited Flickr, which benefits from its shared photo-database and from its community-generated tag database.

    • Level-1 applications operate offline but gain features online. O'Reilly pointed to Writely (now Google Docs & Spreadsheets) and iTunes (because of its music-store portion).

    • Level-0 applications work as well offline as online. O'Reilly gave the examples of MapQuest, Yahoo! Local, and Google Maps (mapping-applications using contributions from users to advantage could rank as "level 2").
