Time magazine says Netflix's Streaming Library is Shrinking Fast
They're down to 4,335 movies. When I joined, they had about 20,000, I believe.
At my peak, I had rated about 3,300 titles on Netflix.com, with star ratings, back when you could do that. I rated only movies I had actually seen.
One of the reasons I quit Netflix was their shrinking DVD collection, and that was a few years ago.
