Space 1999 and UFO Public Domain?

Good Morning All,<br /><br />I recently saw that all the episodes of Space 1999 and UFO are on YouTube in an unaltered format.  While I wish I had a link to paste, I'm at work and it's at home. However, I had read that no one had purchased the rights from the Andersons, and with their deaths, the rights died with them.<br /><br />Anyone else hear about this? I've been watching them, just in case they go away.  I had forgotten just how awful an actress Barbara Bain truly is.<br /><br />Thanks =)
