As the open source operating system turns: way back in March, 2000, BSDI bought Walnut Creek CDROM, and thus took over the stewardship of FreeBSD development (to go with their BSD/OS operating system, which is proprietary). In April of last year, Wind River bought out BSDI, getting both BSD/OS and FreeBSD. Now, Wind River is selling the FreeBSD stuff to FreeBSD Mall, which is owned by Bob Bruce, the original founder of Walnut Creek CDROM.
