In 1977, the TCP/IP was effectively used to link several networks to the ARPANET. More than a hundred computers were connected, and from this point, the number would continue to increase year after year.

In March 1989, Tim Berners-Lee, a computer scientist at the CERN (European Council for Nuclear Research), advised putting documents on the CERN website that were linked by hyperlinks, with the aim of helping physicists searching for information. The origin of the Web dates back to this point in time.

In the early 1990s, the birth of the Internet as we know it today was announced: the Web was defined by a collection of HTML (HyperText Markup Language) pages combining text, images and links that can be reached via a URL (Uniform Resource Locator), based on HTTP (HyperText Transfer Protocol).

In 1991, in Geneva, Tim Berners-Lee developed the Internet interface known as the World Wide Web (WWW), allowing the network to be opened up to the general public by facilitating website consultation instructions.

In 1991, 300,000 computers were connected, with this figure reaching 1,000,000 by 1992.

In 1992, the first link (known as a hyperlink), enabling access to the CERN’s Internet site, was built on the Fermilab server in the United States: this was the beginning of the weaving of the WWW. The Net continued to expand at an exponential rate during the 1990s under the impetus of the Web.

The year 1993 saw the birth of the first web browser, designed by Netscape, which supported text and images. That same year, the National Science Foundation (NSF) founded a company to enable the registration of domain names.

In 1993, there were 600 sites, with this figure exceeding 15,000 by 1995. Today, the WWW has come to be the most valued service on the Internet.

As of 2008, there were 1.5 billion Internet users worldwide, 1.3 billion email users, 210 billion emails sent daily, 186.7 million websites and 133 million blogs.

E-commerce revenues exceeded $2,300 billion in 2017 and are expected to reach $4,500 billion in 2021.
