So when TPTP shut it all down after over-saturation was the franchise in peril or dormant or even dead?
No, because fans keep it going and TPTB continue to make money off tie-in merchandise of pre-existing shows and movies.
There is a fatal flaw in that argument: Star Trek fans -- I mean those who actually keep it alive by buying stuff or writing fanfic, etc. -- are not enough to keep it going.
Paramount didn't make a new Trek movie because the fans buy merchandise: they did so because the franchise is a venerable one that they know will make money because it's so well-known.
But without series or movies, it's not really "alive", is it ?
