Most of the video sites I know of in detail or have researched
do not use Akamai or other local caching services. (Youtube uses  
Limelight for delivery, for example, as AFAIKT they do no caching  
outside of that network. Certainly, the Youtube video
I have looked at here through tcpdump and traceroute seems to transit  
the network.)
And P2P services like BitTorrent do not conserve network bandwidth.  
(Although, they might in the future.)

What does save network bandwidth is progressive download; if people  
actually look at what they downloading,
they may stop it in progress if they don't want it. (I know I do.)
