FreeBSD’s 30th birthday presents an opportunity to look back and examine why this open source operating system has not only endured, but thrived across many organizations and use cases for so long. While open source projects are born out of different circumstances, FreeBSD grew from a mold of its own. The path the project took has everything to do with its longevity and why, 30 years after FreeBSD launched, you’ll find FreeBSD code helping to power everything from your content on Netflix to your games on PlayStation.
BSD (before the Free)
Initially released in 1993, FreeBSD is rooted in the Berkeley Software Distribution (BSD) code base that had been under development since the 1970s. The pioneering BSD project introduced the socket networking interface, the first implementation of TCP/IP, file systems including VFS, FFS, and NFS, the mmap memory model, and more. While BSD was not open source, its licensed code still received many contributions from academic and industry users.
