I mentioned it, maybe it's my fault for not being more clear.

Quote:At the same time the university had created the TCP/IP networking code
and many were asking them to release it outside the AT&T code, which
was the company holding the Unix licensing and trademark.
Thus, in June 1989, Berkeley released their networking code under a
free license.

Here's from wikipedia:

Quote:The spread of TCP/IP was fueled further in June 1989, when AT&T agreed to place the TCP/IP code developed for UNIX into the public domain. Various vendors, including IBM, included this code in their own TCP/IP stacks. Many companies sold TCP/IP stacks for Windows until Microsoft released a native TCP/IP stack in Windows 95. This event was a little late in the evolution of the Internet, but it cemented TCP/IP's dominance over other protocols, which began to lose ground.[citation needed] These protocols included IBM Systems Network Architecture (SNA), Open Systems Interconnection (OSI), Microsoft's native NetBIOS, and Xerox Network Systems (XNS)

Quote:BSD received a big boost from the United States Department of Defense, who selected BSD as the base system for implementing TCP/IP and what became the Internet. The TCP/IP code was made freely redistributable via Networking Release 1 (Net/1) in 1989.
