(Nor worse, though it sometimes was.)

NTSC = Never Twice the Same Colour. NTSC TVs had (still have?) a "Hue"
control for the user to twiddle when skin tones started looking a bit
green.

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.
