Netflix, Reed Hastings Survive Missteps to Join Silicon Valley’s Elite:

The master copies of all the shows and movies available to Netflix take up 3.14 petabytes of storage space. (In comparison, Facebook uses about 1.5 petabytes to store about 10 billion photos.)

This is presented to make the point that “Netflix use a lot of space”. But I see it more as “Facebook is already 50% the size of all of Hollywood’s output ever”.
