Internet - The Origins of the Web

In 1957 the Soviets launched the first artificial satellite into space. Now aware of their technological deficit, the Americans work on a number of programs, including one for computer networks for military use: the ARPA. The mathematician, Lawrence G. Roberts, develops the system into ARPAnet, which enables information to be exchanged between computers over the telephone network.
At the end of the 1980s, the military part of ARPAnet was split off from the rest of the network, which opened up to individuals and businesses.

The grain of sand at the heart of the episode:
In 1991, Tim Berners-Lee created the World Wide Web, which makes navigation from one Internet page to another possible without typing in a single line of code. Better still, he provides access to the source codes of his creation. Now, nobody will ever be able to sell the heart of the Internet. Tim Berners-Lee has just bequeathed it to Humanity.

The consequences of this event:
The Web designed by Tim Berners-Lee and the first hackers necessarily evolved into the Web 2.0.
It is no longer regarded as a collection of sites to be visited, but as a platform providing exchange between users. It’s an explosion: blogs, wikis, social networks, search engines, etc.
Through these communities, the tribal mechanism finds a formidable tool in the Internet.
By standing out against the consumer society, Tim Berners-Lee made all this possible.
