Douglas Engelbart and his team’s demonstration at the Stanford Research Institute (SRI) in 1968 was a game-changer in the world of computing and how we interact with computers. This event marked the first time we saw practical uses of concepts like the graphical user interface (GUI), hypertext, and real-time collaboration. Engelbart introduced the “oN-Line System” (NLS), which included tools such as the mouse, text editing features, and the ability to link documents together through hypertext. These innovations moved us away from traditional command-line interfaces, making computers much easier to use for everyone. By emphasizing the importance of enhancing human abilities and teamwork, Douglas set the foundation for the modern computing environment we rely on today.
