"George Pughe's Pass" was first published in the Kaufman & Greenberg 1994 expanded edition of John Northern Hilliard's Greater Magic. Dorian Rhodell then popularised it on his DVD Avenue. In this original form, it had also been published as the "Wow Control" by Oliver Macia on the DVD Control Freak, presumably as a case of independent invention. In these instances, the move is used as a control, rather than a change.
The original Cardini Snap Change was published in Jean Hugard's Card Manipulations No. 3. In this case, the change was done from a third-finger break, rather than the no-break technique popularised by Dan & Dave Buck in The Trilogy DVDs. The no-break technique was used by Ray Kosby in his Coffin Change from Stephen Minch's Spectacle (with credit to Cardini's original), and independently invented by Daniel Garcia for his Ego Change.
The technique has also been used as a method of palming by Maurice Rooklyn and Jim Steranko.
