As a brief introduction, the web can be separated into three phases:

Web 1.0 is where it all started. From the depths of CERN came the first version of might be the greatest invention of a whole generation. But at first you could only See the content that was presented to you as a document (with the much known HTML).

But that wasn’t enough.

With the introduction of technologies like AJAX and RSS we could actually Interact with the web. And with this came the foruns, social networks, Wikipedia, etc.

The Web 2.0 was upon us.

Web 3.0

But some of the greatest minds didn’t want to stop there. They wanted a Web that not only presented information but also understood it. If you have some time to spare see the video below from Tim Berners-Lee (you now, the mastermind from the depths of CERN that created the Web).
