Can you name a magician that lives over 100 years ago? did you say harry houdini? houdini was the master of the unique selling proposition (usp). in his case, a usp was a new illusion that nobody had ever seen before. houdini was a marketing genius. you can probably name one of his usp's more than 100 years after it was introduced. can you name one of his illusions?
did you think of the chinese water torture cell?
his usp's worked, and he attracted large audiences. of course, other magicians were always copying him and ripping off his ideas. can you name any of his contemporaries? not unless you're a magician yourself.
being first with a string of usps is a powerful tool advantage. don't worry about being copied, worry about being great.
