– Facebook monthly electric bill = US $ 1,000,000/= & adds new servers every few days because users’ appetites for adding photos keeps growing.

– Youtube monthly bandwidth consumption = 25 PetaBytes (1,000 TeraBytes).

I don’t have the exact amounts but the above is a harsh reality of operating such services. Though their financial standings show as mighty, I wonder how long they can sustain just running on large adverts?
