   Locally, perhaps. But Ernie Kovacs was doing chromakey 
effects back in the mid-fifties. One of the first matting 
amplifiers, which produced a luminence key effect (which is 
like a chromakey, only adds signals via b&w blanking [or 
matting] signals) that inspired Kovacs was actually built back

Kovacs stared out.
