[BC] need a NON-technical explanation

[Steve Schoon]

One of the first broadcast engineers I talked to back when I was a young pup
told me that the term Hertz was deliberately avoided during and after WWII,
because Hertz was a German...

Urban legend??

I was one of those that resented this 'change' thing
when  'kc'  was changed to 'kHz' circa 1965 or so here
in the U.S.   The rest of the world was already way
ahead of us.
