Who first demonstrated word processing and hypertext capabilities?

The correct answer is Doug Englebart, who is renowned for his pioneering work in the development of early computer technologies, including word processing and hypertext capabilities. In the 1960s, he demonstrated the oN-Line System (NLS), which introduced several revolutionary concepts such as the mouse, graphical user interfaces, and the ability to link text in a networked environment—what we now understand as hypertext.

Englebart's famous demonstration in 1968 at what is often called "The Mother of All Demos" not only showcased word processing features that allowed users to create and edit documents but also illustrated how different pieces of information could be connected through links, foreshadowing the way content is structured on the modern web. This demonstration was pivotal in laying the groundwork for the further development of personal computing and online information retrieval systems.

While figures like Robert Taylor and organizations like Xerox PARC contributed significantly to the development of computer technology and interfaces, it was Englebart's specific innovations that directly related to word processing and hypertext, making him the key figure in this context. Steve Jobs played a major role in popularizing many of these technologies later on, but the foundational work by Englebart predates this and directly correl
