There is no evidence the Star Trek Universe isn't financially sustainable.
I mean, there might be.
The thing of it is, almost six years into its lifespan now if you count the days when it was called CBS All-Access, Paramount+ still has never turned a profit.
Now, that's not necessarily evidence that the "Star Trek Universe" concept of having three or more shows in constant production and new episodes almost every week of the year is not financially viable per se. Because, after all, none of the single-studio streamers have turned a profit. And all of them were run with the plan to operate on a deficit for the first few years while they built up a large enough back catalog to entice year-round subscribers.
All the single-studio streamers are now coming under pressure from Wall Street to start cutting costs and turning a profit before their initial plans called for them to stop deficit spending. But that doesn't mean the plan would have worked if they'd stuck to it either.
The question is whether or not that business model is viable, period.
I have always suspected that the entire concept of a single-studio streamer never really made financial sense. To make a comparison, back in the '90s, you didn't go out to the single-studio VHS rental stores. You didn't go to the Paramount Home Video Rental Store for a copy of Forrest Gump and then to the Disney Home Video Rental Store for a copy of The Lion King and then to the 20th Century Fox Home Video Rental Store for a copy of The Empire Strikes Back. You went to Blockbuster or Family Video or Hollywood Video or whatever, and they had copies of all three -- because the value came from having a wide variety of content from a wide variety of studio. I think that's ultimately why Netflix and Hulu are going to be more financially viable than Paramount+ or Disney+ or whatever.
But.
That again doesn't mean that the idea of year-round Star Trek content is not financially viable. If Paramount+ folds, it's entirely possible that Paramount could cut a deal to continue year-round Star Trek production to be carried on Netflix or Hulu instead. And I suspect that that might be more financially viable for Paramount than trying to do it on their own streamer.
