Tim Berners-Lee created the World Wide Web in 1990 while working as a computer scientist at CERN, the European particle physics laboratory. He developed the concept of hypertext transfer protocol (HTTP) and hypertext markup language (HTML) to share documents across the internet. The web has since grown exponentially, from 1 website in 1990 to over 162 million websites by 2007. It has become deeply integrated into our lives, changing how we get news, do banking, and connect with others online.
