When you tune into Netflix you might not be aware that the box in your living room starts a complex set of negotiations with servers on moving 563 Gbytes of information into your residence. That is equivalent to having 15,000 copies of the Encyclopaedia Britannica dumped into your home! So, why is watching a Netflix film not the equivalent of the Amazon-delivery from hell?
