Origins of TCP/IP Continued
Researchers at other organizations used the information gained from the project to create their own TCP/IP networks.
The DOD funded two additional projects. The first was the adaptation of TCP/IP to work with UNIX. The second was the inclusion of the TCP/IP protocol with Berkeley UNIX.
At the time, 90% of the university science departments used BSD UNIX, so TCP/IP quickly increased in popularity and use.
This network interconnected so many different organizations and sites that it became known as the Internet.
Since taxpayer money funded the project and the government did not classify it, it was considered public domain.
