Collaborative computing was envisioned by American engineer and inventor Douglas Engelbart as early as the 1960s. Since his first demo, “The Mother of All Demos,” in 1968, many unified communications and collaboration tools and technologies have emerged and evolved, from screen-sharing to SharePoint to Slack. Google Docs debut in 2006 could be argued as a key milestone in mainstreaming digital collaboration, allowing multiple users to work in a single document at the same time.
