A few years back there was a device that would detect the Color SubCarrier
transmitted by the TV Station.  Apparently, if you were trying to tape
a B&W movie (i.e., late at night), it would detect the switch from
the B&W movie to the COLOR commercial, and would then stop the tape
(using a hardwired pause line - this was about 6 yrs ago).  It was
supposed to be pretty fast, but I wonder if the station would just
transmit the color subcarrier anyway during the movie (to avoid this 
effect).  I think VIDICRAFT made this box, and it was called "The
Commercial Eliminator" or something like that.

Of course, this wouldn't do squat for a color show.....
