Next we need a thread on what all they crammed into the NTSC TV signal. Like
PRO audio which was another SAP essentially, the VITS or VIR, closed
captioning, ghost cancelling reference and who knows what else.

Man's innate lust to cram as much as possible into any given bandwidth.

With TV, they wasted it.

Actually, NTSC color makes pretty good use of bandwidth when you're
constrained to all-analog, vacuum-tube technology. When it was
introduced, compatible color was right at the cutting edge of (or maybe
a bit beyond) technical feasibility for commercial (not to say consumer)
electronics.

And ATSC 1.0 color gamut is actually a hair smaller than
that of the NTSC it replaced.
