Netflix’s Secret Special Algorithm Is a Human
Hollywood Video's corporate office had a guy, one guy whose job it was to just watch movies. He'd watch them, make sure it was categorized properly, then create associations with other movies that "you might like" if you like this movie, and vice versa. All kept in a spreadsheet that we later plugged in.We also thought there should be an algorithm, but he was pretty dang good at what he did.
