Yeah, more like Netflix (and we might as well add Amazon here) became popular because of "the long tail". Once, I could easily find 1930's classics like "Stella Dallas" on Netflix (and early Ultravox! on Amazon when they would have to be ordered from brick and mortar music stores at the time).
For some reason (perhaps because it costs money to keep a large catalog?) Netflix retracted the long tail while Amazon at least kept theirs unfurled.
My guess is that Netflix is tried to cultivate a semi-premium brand (but not premium in an Apple TV+ way), which means getting rid of the long tail in favor of what's hip, sexy, exciting, etc. Whereas while Amazon is making expensive boondoggles like Ring of Power, they are also comfortable with keeping dozens of conspiracy theory documentaries on. I guess that's in line with the identity of their main store, and the concept of Amazon being a series of warehouses.
