A question for our UK/EU members concerning electronics

I was reading up about obsolete electronics today, as I am wont to do, when I started looking into SCART connections. It specifies that these were primarily a European thing, and I've honestly never seen one in the US, but reading about them it's obvious they had superior video quality to anything available here in the US prior to component, though for the life of me I can't seem to find information on WHY they didn't pick up in the US.

So, anybody know why? I'd like to know, if just to sate my curiosity.
