This is not the first time Polaroid Spectra film becomes discontinued. The first time was when Polaroid went under and the remaining stock depleted. DPReview now reports that Polaroid Originals is stopping the production of Spectra film because the remaining cameras are now aging, unrepairable, and there is nothing they can do about it.
This is a bigger problem with film photography in general that I wrote about previously: the whole production supply chain, from cameras to film processors and scanners is in danger. Nobody develops new hardware, because it requires a lot of R&D and the old one is becoming harder and harder to repair, non withstanding for processors and scanner where the software is antique and only runs on obsolete systems.
