NTSC was the best compromise of all the world's television systms. However, it had a few drawbacks that linger till today. The choice of 3.579545 Mhz for the color subcarrier
still causes work arounds being sought in the conversion of NTSC programs to PAL and the various SECAM standards, not to mention all the modern digital standards because of the vertical frequency being 1000/1001. This leads to the need for "Drop Frame Time Code" to keep things in sync. The 1000/1001 choice was made to protect a few hundred thousand B&W non-intercarrier TV sets from the early 1950s which showed moire in the pictures when displaying the original choice of color which used 3.583125 as the color subcarrier frequency. Finally, if David Sarnoff had gone immediately to a non-compatible [with NTSC 525-60] color system, we would have had color much earlier. It took until 1970 for color to really catch on and become popular. That only happened because of the 12 inch Sony 12 inch Trinitron TV. THAT'S MY STORY and I'M STICKING TO IT!!!
