TV is completely different than the 90s and when Enterprise was on the air. Back then live viewership ratings and demographic was hugely important because of advertising revenue. For network shows, it is still important but the viewership levels have reduced exponentially since then. However, streaming series have to be viewed with a different model. They are mostly paid for with subscriptions and the amount of subscriptions needed is far lower than the number of viewers needed on network television for ad revenue. That's how HBO survived on shows like The Sopranos and how AMC could afford to have Mad Men on for 7 seasons and Breaking Bad on for 5 seasons. Their viewership ratings don't compare and yet the budgets are often higher. The creative freedom is greater. It's all because of the subscription model.
Star Trek Discovery's premiere had 9.5 million viewers on network TV in the US. How many of those viewers subscribed to CBS All Access? Even if it's "only" 3 million, that is hugely successful for a subscriber based service. Now let's factor in the 180+ other countries it airs in (first time ever this has happened where a new Star Trek episode has aired in that many countries within 24 hours of it first airing) and it turns out Star Trek is a huge success. There's no way CBS would have 4 series officially in various stages of production, with a possible 3 more in development, and be losing money. They're not a charity, they're a business. I bet the Michelle Yeoh series' Chinese audience will pay for the show by itself. Also, think of all the new fans these shows will attract to the greater Star Trek universe.
I understand all of this. Here's the problem:
I currently pay for Netflix. I get a lot out of Nefflix. My kids have their own accounts and watch some shows almost every day. I watch less - mostly old Trek, documentaries, and some sci-fi shows. But I get my money's worth for sure. I have Amazon Prime for other reasons mostly, but they have a wide array of older content (Babylon Five, BSG, etc) which I watch sometimes, and they'll have the next season of The Expanse too.
CBS All Access right now has Discovery for me. Just Discovery. I'm not interested in anything else. I browsed through the other day, and aside from the Twilight Zone revival, nothing even seemed borderline interesting to me. I'm not a TV guy, I'm a sci-fi guy. More of my free time is taken up by reading books, playing RPGs, or shitposting on the internet than watching TV or movies.
So, at the end of last season of Discovery, I canceled my subscription. I reupped this month and caught up with the Short Treks. I can say with 100% certainty I will drop it again as soon as the season is over. Paying $10 per month for four episodes (or less) of Trek isn't a great deal, but spending $10 per month for nothing is a terrible deal. I can see why they decide not to drop the whole season at once, Netflix style, because with their limited content I would just pay for a single month and be done with it. In order to keep people like me on CBS All Access, they'd need to have close to - if not exactly - 12 months a year of exclusive content that I was interested in. It wouldn't have to be Trek, but it probably would have to be SFnal, because frankly I don't give a flying fuck about police procedurals or sitcoms. They're a waste of time for me.
So yeah, I will check out all the new shows when they come out - give them a chance. But if they aren't my cup of tea, I'm certainly not going to watch episode-by-episode come their second seasons. I'll watch them between episodes of Discovery, or the Picard show, or whatever. Which means that instead of getting $120 a year out of me, they might only get $40-$80. Which means significantly less revenue going to CBS All Access, presuming there are lots of people like me.
Again, as a fan of the franchise, I don't think there's anything wrong with the creation of Trek series which aren't really appealing to the modal fan. But if the idea behind expanding this exclusive content was to woo die-hard Trekkies into continually being subscribed, I think it's wrong-headed, and won't make them anywhere near as much money as they think it will. It seems that once again CBS is trying to forge an awkward middle ground between broadcast TV and exclusive streaming services - a middle ground which is fraught with peril.
