An umbrella term for the second wave of the World Wide Web, which was coined in a conference on the subject in 2004 by O'Reilly Media and CMP Media (later taking its parent name of United Business Media). Sometimes called the "New Internet," Web 2.0 is not a specific technology; rather, it refers to two major paradigm shifts. The one most often touted is "user-generated content," which relates more to individuals. The second, which is equally significant, but more related to business, is "cloud computing."
#1 - The User Rules!
User-generated content, comprised of blogs, wikis and social networking sites, such as MySpace and Friendster, let everyone have their say on anything and publish it to the world at large. As Web applications become more sophisticated, people can easily develop elaborate personal Web pages, create a blog, and upload their own opinions, audio and video. Users are augmenting the news by reporting current events sometimes faster and with details often overlooked or ignored by the professional news media.
Although millions of opinions and videos, often very amateurish, only add to our information overload, a significant advantage to user-generated content is that truly talented authors, artists, musicians and moviemakers can gain an audience much more easily than they could in the past. Word-of-mouth via the Internet is worth a fortune in promotion. Web 2.0 is leveling the playing field in all arenas just as the PC leveled the playing field in business. See hot topics and trends, blog, wiki, social networking site, MySpace, user reviews, YouTube and paradigm.
#2 - Cloud Computing
In cloud computing, also called "thin client computing," data and applications are stored on Web servers, and a user has access from any computer via a Web browser. Many believe that cloud computing will eventually supplant locally installed office and other applications and that turning the Web into a gigantic application server is the ultimate manifestation of Web 2.0.
In time, this could have significant impact on the type of personal computers users choose. As more software is executed from scripts embedded in Web pages, the CPU chips and operating systems become less relevant. Browsers interpret scripts the same regardless of the hardware and software environment they reside in (most of the time, that is!).
In 2007, Google combined several of its office applications into Standard and Premium Editions, the latter a paid service with tech support. Because of Google's influence, this was a watershed event for cloud computing (see Google Apps). See ASP, Web application, thin client and Enterprise 2.0.
What Caused Web 2.0?
Bandwidth and power. Faster in most cases than the T1 lines in the enterprise, cable and DSL hookups have extended high-speed connections to individuals and small businesses. Browsing Web pages full of images and video as well as downloading multimedia files have become routine.
In addition, entry level computers became powerful enough to execute scripts in an HTML page without noticeable delays. Combined with refinements in Web programming (see AJAX), the Web has become a transparent extension of an individual's PC just as local area networks (LANs) extended the user's computing resources inside the enterprise in the 1980s and 1990s.
Web Evolution
In the mid-1990s, the Web began (Web 1.0) as a repository of information and static content. Within a couple years, a huge amount of content was dynamic, returning custom results to users. By the turn of the century, the Web became much more interactive (call it Web 1.5), allowing users to play, stop, rewind and fast forward through audio and video content. Web 2.0 makes Web-based applications feel like and run as smoothly as local applications. See Web 3.0.
