According to Justin Mitchell, an engineer working on Facebook Photos, on January 25 2011 the social site had a collection of 90 billion duck face photos. Even more impressive, however, was the rate at which new photos were being added: 200 million each day, or around 6 billion per month.
Eight months have passed since then and if the growth rate for photo uploads has kept that trend Facebook should now have a collection of over 140 billion photos – making it the largest photo archive in the world.
To give you an idea of how insanely huge that is, it’s 10,000 times larger than the Library of Congress and represents 4% of all photographs ever taken. To be fair, though, the remaining 96% of photos are probably split between porn sites (95%) and everyone else (1%).
