The “Mother of All Demos” was important because it was a major breakthrough in computer technology. It featured an early computer mouse which used a planimeter to monitor rotation. Englebart also showed the oNLine System (NLS). The NLS allowed shared files so that multiple could read the content. Englebart demonstrated how he could type, delete, copy, paste, and move text on the screen. He showed how he could add hyperlinks. The NLS also allowed for video conferencing.

Englebart’s demo was extremely ahead of its time, and people hadn’t seen anything like it. The “Mother of All Demos” is one of the most important and revolutionary progressions in computer history. His work inspired future technology, and is vital to how computers have progressed to where they are today.
