Personally, the only thing I ever watch on Netflix now is the new Israeli TV stuff -- Fauda, Mossad 101, etc. I think this is one consequence of them shifting to being a "channel" with their own content (which I mostly don't care for).
Almost all my streaming is with Amazon Prime, which has a much bigger selection of content suited to my tastes.
Dialing in a little, they peaked out at something like 40% of all US internet traffic 4-5 years ago.
