NLS 1
Doug Engelbart first envisioned his work in the 1950s, published it in 1962 with a call to "augment the human intellect", and hired a small team of researchers to develop a demonstration hyper collaborative knowledge environment system called NLS (for oNLine System), first published and publicly demonstrated in 1968 (see the Mother of All Demos), and continued to evolve it under real world usage with a team of up to 47 researchers in his now legendary lab at SRI (Stanford Research Institute, now SRI International), cultivating a networked community of early customer IT pioneers (called "KWAC" for Knowledge Workshop Architect's Community, the first intentional NIC) via the newly formed ARPANet.

Note that the basic funcitonality of NLS was envisioned at a time when the nearest computer was 3,000 miles away, and implemented at a time when the human-computer interface consisted of punch cards and teletypes, with clumsy line editors to support elite scientific and mathematical applications. So Doug's lab had to prototype much of the underlying technology – for example they pushed the frontiers in display technology and invented their own high-performance pointing devices (thus was born the Mouse, invented by Engelbart in 1964), and participated in launching the first computer network so they could leverage network technology for their collaborative applications –as well as needing to develop their own paradigm and vocabulary for this work.
