TTR from Pittsburgh writes: "Several months ago I did what I believed was an exhaustive search of Netflix, I looked at all of their categories and subcategories as well as doing a systematic alphabetical search of their site and I dont believe they have anywhere near as many movies as they claim. I called when I could no longer find a movie on their site that I hadn't rated and they were over 10,000 short of the movies they claimed to have."
I asked Netflix about this, and a spokesperson explained how they count titles:
"Netflix’s list of titles counts every title on the website, including those not yet available on DVD but that we have SAVE queues for, such as current theatricals and movies currently on moratorium on DVD. It also counts individual discs in a box set as separate movies since each disc has the content of a full-length movie."
