Wasn't it first assigned to the new FM broadcast band, before that was
moved to 88-108 MC?

A number of TV sets were manufactured with a channel 1 on their dials. 
I have one and have seen others.

You mean they really moved channels 2-4 down?  I'd never heard that;
I assumed the 4 MC gap was always there.

I guess these things all must've happened around WWII, when there was
no TV broadcasting to speak of.
