Howdy Doody was using chromakey around 1955-56.  They were one of the
first shows to be colorcast regularly, and I remember they used those
effects for various purposes.

I remember one scene when one of the human (i.e. non-puppet) characters
was putting on his invisibility suit.  It was pretty obvious that he
wasn't actually on the set that appeared behind him.  I suppose he was in
front of a blue background, and his invisibility suit was actually a blue
suit.  Looked good, too.
