I found the trailer for the upcoming season of Masters of Illusion and you get to see a trick I invented at the 27 second mark:
One of the great things about creating original material, not just presentations is that when you are pitching acts to a TV show you don’t have to worry if something has been done before. This applies to more than just TV, it’s a huge advantage for variety shows as well. You don’t need to fight over who gets to do what trick.
Original content is king!
