By now, Everybody who are working with web technologies atleast might have know what is Web2.0 and what are the technologies involved with this and where we can implement these concept. But here is the interesting topic on how this web2.0 came into Web world? Ok lets discuss below:

The concept of “Web 2.0″ began with a conference brainstorming session between O’Reilly and MediaLive International. Dale Dougherty, web pioneer and O’Reilly VP, noted that far from having “crashed”, the web was more important than ever, with exciting new applications and sites popping up with surprising regularity. What’s more, the companies that had survived the collapse seemed to have some things in common. Could it be that the dot-com collapse marked some kind of turning point for the web, such that a call to action such as “Web 2.0″ might make sense? We agreed that it did, and so the Web 2.0 Conference was born.

This article is an attempt to clarify just what we mean by Web 2.0. See the below technologies which are in web2.0 and from what concepts in web 1.0 they came from..

All the above concepts are existing but came again with fresh look and added features and advantages. You can see some of the examples below on their evolution:

Wikipedia:

• Wikipedia, an online encyclopedia based on the unlikely notion that an entry can be added by any web user, and edited by any other, is a radical experiment in trust, applying Eric Raymond’s dictum (originally coined in the context of open source software) that “with enough eyeballs, all bugs are shallow,” to content creation. Wikipedia is already in the top 100 websites, and many think it will be in the top ten before long. This is a profound change in the dynamics of content creation.

Social Networking Sites:

• Social Networking Sites like del.icio.us and Flickr, two companies that have received a great deal of attention of late, have pioneered a concept that some people call “folksonomy” (in contrast to taxonomy), a style of collaborative categorization of sites using freely chosen keywords, often referred to as tags. Tagging allows for the kind of multiple, overlapping associations that the brain itself uses, rather than rigid categories. In the canonical example, a Flickr photo of a puppy might be tagged both “puppy” and “cute”–allowing for retrieval along natural axes generated user activity.

Search Websites:

• Yahoo!, the first great internet success story, was born as a catalog, or directory of links, an aggregation of the best work of thousands, then millions of web users. While Yahoo! has since moved into the business of creating many types of content, its role as a portal to the collective work of the net’s users remains the core of its value.
• Google’s breakthrough in search, which quickly made it the undisputed search market leader, was PageRank, a method of using the link structure of the web rather than just the characteristics of documents to provide better search results.

So thats how the Web2.0 came into picture with having the contrast between the older technologies and new ones.
