The Future Internet: Service Web 3.0

QuickTime player required to watch the video. http://www.apple.com/quicktime/download/

Web 1.0 was about displaying/getting information so that it can be accessed by users that are connected to the internet. For example a user looking for "MIT", would get details about MIT by visiting website of MIT.

Web 2.0 was about users contributing to the growth of information on the internet. For example facebook , myspace, orkut, blogger.com, twitter.com In all these web applications users were heavily involved in providing data or content.

With Web 3.0 "Every possible electronic device will be connected to internet and it will be possible to communicate with every possible electronic device over the internet"

The whole idea of Web 3.0 is to take internet from mobiles and personal computers to every possible electronic device so that it can be controlled by the user using the internet. For this the internet has to re designed as its not possible currently, for all types of electronic devices to communicate with each other, For example how can a mobile phone communicate with your washing machine, for this the data format has to be understood by both washing machine and your mobile phone.

With Web 3.0 i will be able to switch off all the lights @ my home from my mobile phone as i keep forgetting to switch them off after i leave to office.

In short everything and everybody will be connected and able to communicate with each other seamlessly.
