LOL. The US system was truly dire for terrestrial broadcasting and only
just acceptable for cable.

Ah, but NTSC had a far reaching impact that had nothing to do with TVs.
Because of the TV consumer market 3.57954 MHz crystals were dirt cheap and
showed up everywhere. I believe some variant of the 8253 PIT still lives
in PCs and runs at 1/3 or 1.19318 MHz. Roll the 16 bit counter over and
you had the 55 msec tick.

Yup. In the UK/Europe the crystals for PAL were 4.something MHz
I use them in a digital design.
 

PAL crystals were used in some markets to be compatible with the TVs but
never had the off label reach.

 I don't actually understand that statement

   I suspect he means that NTSC crystals were handy
   and thus used in MANY devices - driving down the
   price and enhancing availability. Kinda like the
   baud generator for modems, 32.768 Khz, that were
   also used in electronic clocks/watches ... they
   likewise became 'ubiquitous'.
