re: chyron: "That's the technical name for the letters/graphics a television station puts on your screen 'on top of' the picture."

If you want to be precise, Chyron is a trademark for a device that superimposes electronic graphics on a television image...and is kind of like Xerox to photocopies.

I didn't really want to be that precise. ;O)

I would just point out that kleenex is to tissue and band-aid is to 'adhesive bandage' as chyron is to 'superimposition of electronic graphics on a television image.'
