Well John, can one OTA station serve 10 million customers? In terms of
bandwidth yes, but unfortunately it doesn't have the coverage for the
entire country. So by direct comparison, OTA doesn't work either.
Your argument is pointless since the same mechanisms are used for
internet video delivery as are used for broadcast delivery, i.e. there
is a single contribution source delivered to multiple endpoints which
then in turn farm it out to geographically dispersed locations.
Only a fool would attempt to serve that amount of viewers from a
single datacenter without using geographical and pop-based dispersion
of the data to multiple edges and origin clusters.
