HTML was invented by Tim Berners-Lee in the 1980s. While working at CERN, the European nuclear research center, he developed a system called "Enquire" that allowed scientists to share information with each other. Enquire was based on a simple markup language that later became known as HTML. In the 1990s, the World Wide Web Consortium (W3C), founded by Berners-Lee, began standardizing HTML. The first version of HTML was released in 1993 and since then the language has continued to evolve. Today, HTML5 is the current version of the language and is supported by all major web browsers.
