I mean TikTok’s “magic” algorithm should be considered innovation here as well, and it has been quickly copied by Reels, Shorts, and whatever Snapchat has. Although I am pretty sure YouTube’s is still mainly just channels you follow. It was the first I’m aware of that learns your preferences from purely passive interaction (i.e. not liking and subscribing, not following topics, not relying on a social graph). I put magic in quotes because if you read their paper it’s nothing too crazy but (ignoring the addictive quality) it still feels pretty cool.
