Internaut is a term for a designer, operator, or technically capable user of the Internet. Beginning with participants in the Internet Engineering Task Force (IETF), it gradually expanded to members of the Internet Society (ISoc) and the larger community.
The Internaut day is celebrated on August 23, anniversary of the WWW - World Wide Web, which was developed in the CERN laboratories (Enquire / EV project) in Switzerland during 1989 - 1990, and opened to new users after that day in 1991.
The WWW creation by Tim Berners-Lee enabled non-technical computer experts to use the Internet in a simple and quick way, making it accessible to billions of people around the world: the internauts.
Sir Timothy John "Tim" Berners-Lee is an English computer scientist, best known as the inventor of the World Wide Web. He made a proposal for an information management system in March 1989, and he implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet sometime around mid November of that same year.
