Sorta related story.

I worked for a cable channel (TechTV) in the late 90s early 2ks (until Comcast bought it, laid everyone off and turned it into G4) this was the early days of cable VOD. At that time you had to pay a service by the minute to watch your video before they’d distribute it. That was the QA forced on you by the cable companies.

The fun note is that those services charged double for “adult” content.
