Close enough - My CET testing back in the 80s taught me the NTSC standard is actually 15,734 Hz....

Probably the best explanation on the web:

And the vertical rate is actually 59.94 Hz....

It was a trick question on the ISCET Journeyman CET test for Consumer Electronics back in 1987...sadly, even I got it wrong, but still passed with a score of 97.

Zenith Electronics is still around, a wholly owned subsidiary of LG Electronics, which bought Zenith little by little.....
