Polaroid Originals were originally called 'The Impossible Project' and was a kickstarter campaign based around recreating the original Polaroid Instant film.
It ended up being so successful, that they managed to acquire the brand name and IP of Polaroids Instant Camera technology.
They didn't buy the IP for the chemistry for the original Polaroid film though, as Polaroid sold that to Fuji.
That's why there's only 8 instead of 10 photos in a pack, because their chemistry required thicker photos, and the photos take about 30 minutes to self-develop, rather than 30 seconds of original Polaroids or Fuji Instax.

I'd link to a source, but it seems that https://www.impossible-project.com now just redirects to Polaroid Originals.
