This article is true but does a poor job of explaining itself. SGML was invented at IBM before it became an ISO standard. It's purpose is right in the name, Standard Generalized Markup Language. HTML is an application of SGML (this is what IBM called use cases). XML is another application of SGML. It's fair to say Tim invented the HTML application. Hyperlinks weren't invented by Berners-Lee. If Ted Nelson is to be believed, he invented them and was very disappointed in Tim's unidirectional version. Nelson's were two-way links. It is absolutely true that Berners-Lee was responsible for kickstarting the internet we know today by standardizing on HTML + Mosaic (Mark Andreesen) at CERN.
