From the article:-

"conceived of the web in 1989 at the European Organization for Nuclear Research (CERN) as a way to allow scientists around the world to share information with each other on the internet. He introduced a naming scheme (URIs), a communications protocol (HTTP), and a language for creating webpages (HTML). His open-source approach to coding the first browser and server is often credited with helping catalyzing the web’s rapid growth"

So no, not hypertext, not SGML, not MIME: URI, HTML (an application of SGML) and HTTP.
