Web 2.0 is a conceptual term applied to the emergence of a new way of using and thinking about the web. The term was first used in 1999, but it did not become widely used until 2004 after a conference on the topic was hosted by Tim O'Reilly.

History

In her article Fragmented Future, Darcy DiNucci (1999) foresaw the future of the web. She writes:

"The Web we know now, which loads into a browser window in essentially static screenfuls, 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 screenfuls 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."

Web 2.0 emerged during the time of the dot-com bubble burst. By the end of 2002, more than $5 trillion was lost due to over speculation of the value of web based businesses on the NASDAQ [1].

dot.com bubble

Still, over 50% of dot-coms survived the burst[2], and, as DiNucci (1999) predicted, webpages began the transformation from static to interactive.

As usage of the term began to spread, O'Reilly called a conference [3] in 2004 to hash out, debate and discuss it's meaning.

Defining Characteristics

According to O'Reilly (2005) [4] web pages and companies that are truly classifiable as 'Web 2.0' exhibit a number of core competencies.

  • Services, not packaged software or platforms[5]
Web 2.0 products move beyond the packaging through 'value-added' offerings. A good example of this is the difference between the Microsoft Office suite and Google Docs (or Drive, as it is now called). While Office products are only available on the computer on which they were registered, Google's Drive applications can be accessed from any computer or device with a web connection. The service they are providing is accessibility and portability, as well as cloud storage and sharing, something Office is incapable of doing.
  • Control over unique, hard to recreate data sources[6]
"SQL is the new HTML" (Hal Varian) Specialized databases are a significantly important aspect of Web 2.0. As the size (and information footprint) of the web continues to exponentially increase, so must the ability of users access that information. Searchable, indexed databases are the backbone of the web, and they are what makes sites like Amazon, IMDB, and Google Search so accurate and effective.
  • Users as co-developers[7]
  • Collective intelligence[8]
  • Leveraging the long tail[9]
  • Software above the level of a single device[10]
  • Lightweight user interfaces, development models, and business models[11]

Criticism

*

Criticism of Web 2.0 is wide ranging and varied.

Some say Web 2.0 is simply a meaningless buzzword or meme[12] promoted by O'Reilly to renew financial interest in the web after the dot-com bubble. Others argue that the characteristics that make Web 2.0 unique were around long before the early 2000s[13].

It has also been suggested that Web 2.0 is dead, and that we are now entering an era of Web 3.0[14].
