Apart from a few decades of expensive lobbying, the only competitive
thing OTA broadcasting has going for it is that it is OVER-THE-AIR. For
fixed receivers it can't really match the bandwidth of tethered optical
cable lines. But it could be obviously much better at delivering all
kinds of info without wires to things that move.
That much seems pretty obvious to me but it is still unclear whether it
will eventually be done by any of the current broadcasters. They
instead seem to want to pretend to be fixed, along with fixed customers.
This will of course not be work well once all homes are connected by
wires anyway.
Maybe they think if they don't move nobody will notice them. ;-)
