Our digital TVs still have controls with the same basic concept. Something
about adapting to room lighting, preferences. On some digital sets, the
profusion of such controls can be quite bewildering. Many are tucked away in
submenus and protected service menus.

For about the last 20 years of its life, NTSC became very stable.
Adjustments to the picture controls were very infrequent - mostly done when
the TV was set up. For the first 10 years, it was a nightmare.

Correct. I still have one of the first Sony sets to enter the county
which had to use a slight variant of NTSC to get past the PAL patents,
it's fitted with a hue control which in effect rotates the quadrature
subcarrier (as in NTSC) to get the correct skin tones (the wrong colours
being caused by sub-carrier side band attenuation).
