Tim Berners-Lee, known as “TimBL,” is a British computer scientist and MIT professor. As the inventor of the World Wide Web, Berners-Lee now is the director of the World Wide Web Consortium, W3C, and oversees the development of the Web.

On this day, July 7th, in 1990, the World Wide Web was born when Tim Berners-Lee, a researcher at CERN, developed the HyperText Markup Language, which would later be called HTML.

HTML is the main language used for web pages. The text is recognizable by its use of tags enclosed by angle brackets. Web browsers then read HTML documents and create visible and audible web pages from the tags.
