I would imagine that the bandwidth cost also comes into billions, plus
the cost of the power for all the routers and muxes and line systems to
move this stuff, and the terminating devices which send and receive it,
and so on.
In fact, it would be an interesting exercise to calculate just how £much
it costs to move a bit around the world these days, then move up the
layers. The highest costs are probably at the final terminals, with all
that complex graphical processing to display output, but even so, it
*still* all has a cost.
