I find it weird that people don't think of the BBC as a tech company, from their work on microphones way back in the day, to launching iPlayer (before youtube, and launching on christmas day iirc) to regular live streaming of huge events in 4k (something netflix has struggled with). But yet they are never recognised for their engineering.

All of the players in this echelon have contributed massively, and all of them have pretty wild workflows and impressive solutions to technical problems. If we were measuring technical achievement across the broader history of filmed entertainment, there’s a strong case to be made for Disney as the most influential. But when it comes to how content is produced and distributed today, Netflix has definitely invested the most into tackling modern challenges and continues to do so, and these efforts feed directly into the meticulous, end-to-end workflow that’s applied across every production.

There are plenty of people who have worked on Netflix and non-Netflix shows and would would argue that Netflix's workflow and high standards are difficult if you're not used to it yet, or more stringent than they'd like, but very few would deny the end results or technical superiority

the disney studios (walt disney animation, walt disney pictures, pixar, Industrial Light and Magic, Blue Sky, 20th Century Fox) contributed a significant amount of research towards technologies used in film and television, much of it in academic conferences like SIGGRAPH
