[QUOTE=7"estatdef;2837099]The first time I ran into the term was in a 1939 GE H-87 radio manual.
In the 1950s one TV manufacturer included a 'wobbulator' circuit in a few sets to make the scanning lines disappear. It was a ~14 megacycle power oscillator driving a third yoke coil that moved the beam vertically by a very small amount, but just enough that it covered the blank areas between the lines on the screen without making the picture look out of focus.
I don't remember which company did this but maybe someone reading this does???
