Tim Berners-Lee authored the first web page using HTML, which functioned as a readme document explaining HTML’s purpose. He developed it to facilitate easier information and document transfers. His broader vision was to enable researchers worldwide to collaborate by sharing research and documents for direct download to their devices. This initiative ultimately contributed to the establishment of the World Wide Web (WWW), using HTML as its publishing language.
The invention of the web and HTML are mutually exclusive and equally as important without one we wouldn’t have the other, and it all stemmed from the ease of access of information, which all these years later is still its primary use (maybe not how Lee intended though).
