This article is a few weeks old, and at its core is a great Ted Talk from 2016 that compares how Amazon and Netflix used data to create content. The talk is just 12 min long and if you add 5 min for that article (with a lot of newer info), your time is well spent. In a nutshell, Amazon based their decisions on actual reactions of viewers who saw pilots (which they produced after holding a competition), while Netflix did not use (limited) reactive data to existing pieces of content, but reactions & insights about any content watched on Netflix - and created theirs from there. Amazon's result was "Alpha House", Netflix's was "House of Cards".
