Some of the more interesting things from the presentation include the fact that the early distributions of BSD and UNIX were free (as in price and freedom), and that only later did the idea of source licenses appear. In fact, there were no per-machine licenses, but rather per-institution licenses.
Another early thing to note is that BSD was farther ahead of the Commercial System V from AT&T. It had progressed in both popularity and features beyond the commercial releases of System V UNIX. This is in contrast to what the SCO Group have been claiming, and in light of these facts, their claims seem very suspect. You should particularly note is the statement that âLater BSD developments continued to be added to System V by AT&T to keep up.â"
