SyFy was unable to turn it into a source of revenue
I feel like Amazon totally missed the boat on this too.
Like, where was the merch? why didn't they capitalize on the popularity of it? where were the T-shirts, the cosplay outfits, the toys, the model kits? you know the Expanse fanbase would buy model kits.
They have a fucking online retail store, which they control the advertising on, plus every possible contact in the manufacturing industry they could possibly need. Promoting merch for the series would've been so fucking easy, and producing it would've cost them next to nothing compared to the show production.
