More commercial eliminationSubmitted by brad on Fri, 2004-07-09 03:56
In the 80s, as VCRs were becoming popular, I saw an interesting product that acted as a commercial eliminator for those who wanted to tape classic, black and white movies that were often on late at night.
The product simply detected when the signal went colour, and would trigger the pause button on your VCR. (In early VCRs this was not even infrared.) The commercials were colour, the movie was B&W and so you got a commercial free movie recorded.
