Web 2.0 is basically the type of website in which users can visit and change the content of the website to any extent. Users can interact and collaborate with each other through this type of website. The previous technologies of websites only allowed a user to come and view the page and he could not do anything other than reading the content, but thanks to web 2.0 technology now he can now do something other than only viewing that is updating the content in one way or the other. Some examples of web 2.0 websites include social networking websites, blogs, wikis, video sharing websites, image sharing websites and web applications etc. History:
The term ‘Web 2.0’ was introduced in 1999 by Darcy DiNucci, who was a consultant on electronic information design. She wrote in her article ‘Fragmented Future’: “The Web we know now, which loads into a browser window in essentially static screenfulls, is only an embryo of the Web to come. The first glimmerings of Web 2.0 are beginning to appear, and we are just starting to see how that embryo might develop. The Web will be understood not as screenfulls of text and graphics but as a transport mechanism, the ether through which interactivity happens. It will [...] appear on your computer screen, [...] on your TV set [...] your car dashboard [...] your cell phone [...] hand-held game machines [...] maybe even your microwave oven.” Her use of the term was mainly about the Web Design, aesthetic and the interconnection of the everyday objects with internet. She thought that internet was being ‘fragmented’ in different portable devices which could use internet. Her article was mainly for the designer to direct them to code programs for the new increasing pieces of hardware. So her user of the term is near the current use of the term but it did not mean exactly the same as the term today means. No more work was done on this term ‘Web 2.0’ until 2003 when Scott Dietzen said, “the Web becomes a universal, standards-based integration platform”. After that John Robb wrote, “What is Web 2.0? It is a system that breaks with the old model of centralized Web sites and moves the power of the Web/Internet to the desktop”. In 2004, the term again started to gain popularity when the first conference on Web 2.0 was held by O’Reilly Media and MediaLive. In the start of the conference John Battelle and Tim O’Reilly framed the definition of ‘Web as Platform’, where software were to be built on web instead of the desktops. For this unique change they argued that, “costumers are building your business for you”. According to them the activities of users of generating content (in the form of ideas, text, videos, or pictures) will increase the value of their websites and businesses. They both contrasted Web 2.0 with the previous websites which they called Web 1.0. The associated Web 1.0 with the business models of Netscape and Britannica Online Encyclopedia. The said: “Netscape framed "the web as platform" in terms of the old software paradigm: their flagship product was the web browser, a desktop application, and their strategy was to use their dominance in the browser market to establish a market for high-priced server products. Control over standards for displaying content and applications in the browser would, in theory, give Netscape the kind of market power enjoyed by Microsoft in the PC market. Much like the "horseless carriage" framed the automobile as an extension of the familiar; Netscape promoted a "webtop" to replace the desktop, and planned to populate that webtop with information updates and applets pushed to the webtop by information providers who would purchase Netscape servers”. It means that Netscape was focusing on developing, updating a software and distributing it to end users. O’Reilly contrasted it with Google, which did was no focusing on producing software at that time. Google focused on providing a service on data such as web page authors make between websites....
