Roddenberry on DS9
I've always been interested in the continuity of the canon, as it were, from a production standpoint. There are, after all, some "fan" voices who reject anything after TMP or so, and others who reject anything post-Roddenberry.
I've covered this on the main canon page already based on a reference from a book, but this is newer confirmation from the only surviving horse:

He wasn't around to approve scripts and casting, of course, but the concept of a new show, and perhaps even the general parameters depending on how detailed the pitches were, was approved.
