There's a lot of false information floating around. And there's always this undercurrent of television standard nationalism that sort of gets in the way of these discussions. Its always good to remember that these television standards were the best B&W standards the 1930's could provide. And that when color was added, they became the best the 1950's could provide.

PAL & SECAM were developed by learning the lessons that NTSC provided. They tackle similar problems in different ways.

The problem is that over the years so much ground has been covered with the improvement of the various systems, that its hard to really look back and see what the original problems were.

For example, you mentioned saturation problems. The question is, were they really problems with the NTSC standard, or were they problems with the vacuum tube (valve) technology of the time? If so, did those problems supposedly corrected by PAL & SECAM suddenly disappear once the technology shifted to solid state? If so, then it wasn't a problem in the standard, but in the implementation.

I'd be curious though to read more about the problems you describe. I know that especially in the early days no one had a good idea how to correctly setup color systems. ABC TV here in the states didn't even use vectorscopes for color setup. All of the color setup and testing procedures were developed over a long period of time, and often through experimentation.
