You can set channel weighting distributions, add watermarks, schedules, practically anything that you’d want,
But similarly, Amazon has never properly captured the experience of simply browsing the curated shelves of a bookstore or library. I don't think any online service has.
Netflix, for example, basically just pushes the same 10-20 movies and series at you under different headings.
At one time you could browse by categories like "classic TV" but those seem to be long gone.
If you want to see innovation in streaming you need the sort of legislation that prevents that tying. If every show was available on every streaming platform, then they would start to compete on offering the best streaming service and you'd start to see innovation. Right now, there's just no incentive.
