The reason it didn't catch on is that the local stations started using it to close the loop on their transmitter adjustments by inserting it locally. Of course, when they did that, it no longer bore any fixed relation to the original video, just as the locally re-inserted color burst didn't either. So, set manufacturers decided not to use it, as it often made the color worse instead of better. It could have succeeded if GE had managed to get the FCC to mandate its correct use.
