It was TIM BERNERS!
World Wide Web means "a spider web as big as the world." That’s what it is. A cloth weaved with useful thread that connects text, images, sounds and also kinds of documents.In 1990 Tim Berners Lee worked in Ginebra, in the CERN. Habitually he would communicate with his colleagues there and at other investigation centres, sending articles in which in other articles there would be graphics... To facilitate this working process he designed the first version of HTML(Hyper Text Markup Language), language to mark texts that would allow blending with other documents. In 1991, his programme was being distributed spontaneously and for free to the academic world. Everyone found it to be useful and easy to use so the number of users increased rapidly.Soon new versions of HTML were made and commercial programmes, too. In 1994 over 50 million people were using it all over the world. Actually WWW is the most used service on theinernet and it is considered the principal engine in the great expansion of the Internet for private and commercial use.Actually Tim Berners Lee workd at MIT. He is the founder of 3WC, a corporation that works for the growth and normalization of WWW.
