If you had your location filled in properly we might have some idea where you are?.

But most of the world is replacing the old analogue TV with digital TV, giving more channels and (potentially) better pictures, included HD.

The UK started it first, but are doing a staggered switchover, region by region - I understand the USA has done it all in one go, and are having big problems in some areas as they changed working UHF channels to non-working VHF ones after analogue was turned off.
 
I belive NTSC is an acronym for - Never Twice the Same Colour
 
The NTSC system has worked fine for the last 45 years. Its colours were wrong for the first 10 years about 56 years ago.

PAL was first broadcasted 14 years later than NTSC.

That's the problem with been first - the UK was first with TV and had only 405 lines (and less than that pre-WWII on alternate days), the USA were first with colour and so had the poorest system. PAL was essentially a 'cured' version of NTSC, and much better, the UK then leapfrogged over 525 lines with 625 line PAL colour. The USA then seemed to remain static until the jump to HD, mostly missing out on such things as widescreen analogue.

In most respects it's settled down now, with more closely similar standards than ever before.

(we won't mention the old French 819 line B&W system, or their SECAM system).
 
The old analog TV standards followed the political systems of the countries that used them.

SECAM was used in the Soviet union. The Russian population had no control over color level or hue. Only high party officials could control television.

PAL was used in Europe, less socialist, but only gave their populations control over color level. Hue was controlled by the state.

NTSC was the system of North America. Free citizens exercised their God given right to control all aspects of color television, using both color level and hue knobs.

The NTSC TV manufacturers made an "automatic" hue system:
The sky was skin colour.
The grass was also skin colour.
Horrible colours.
