==Sale to Tymshare==
The technology was sold to [[Tymshare]] in 1977, with 20 members of the former SRI group (including Engelbart) becoming Tymshare employees.<ref name="sul"/> Only about three or four people were left to continue the NIC, although this group grew quickly along with the [[Internet]]. [[Jon Postel]] left in 1977 to join the [[Information Sciences Institute]].<ref name="oral">{{cite web|title=Oral History of Elizabeth (Jake) Feinler |author=Interviewed by Marc Weber |date=September 10, 2009 |work=Reference no: X5378.2009 |publisher=[[Computer History Museum]] |url=http://archive.computerhistory.org/resources/access/text/Oral_History/102702199.05.01.acc.pdf |access-date=April 20, 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110811175249/http://archive.computerhistory.org/resources/access/text/Oral_History/102702199.05.01.acc.pdf |archive-date=August 11, 2011 }}</ref> A number of early participants moved on to careers at [[Xerox]], [[Hewlett-Packard]], [[Apple Computer]], [[Sun Microsystems]], and other leading computer companies.

Tymshare renamed the software ''Augment'' and offered it as a commercial service via its new Office Automation Division. At Tymshare, Engelbart soon found himself marginalized and relegated to obscurity. Operational concerns at Tymshare overrode Engelbart's desire to do further research. Various executives, first at Tymshare and later at [[McDonnell Douglas]], which acquired Tymshare in 1984, expressed interest in his ideas, but never committed the funds or the people to further develop them. His interest inside of McDonnell Douglas was focused on the enormous knowledge management and IT requirements involved in the life cycle of an aerospace program, which served to strengthen Engelbart's resolve to motivate the information technology arena toward global interoperability and an open hyperdocument system.<ref>{{Cite web | url=http://dougengelbart.org/about/ohs.html | title=About OHS - Doug Engelbart Institute}}</ref> Engelbart retired from McDonnell Douglas in 1986, determined to pursue his work free from commercial pressure.
