From BSDToday: "Back in March, 2000, BSDI merged with Walnut Creek CDROM, the main distributor for FreeBSD. And BSDI had goals to "form a united front for the BSD operating systems. The company will deliver, support and enhance both BSD/OS and FreeBSD."
Then in April, 2001, Wind River bought the BSD properties from BSDi (and BSDi became the hardware company, iXsystems). "
