Since the publication of his first book, "My Story" in 1975, Geller claimed that his wealth originated from being commissioned as a mineral-dowser. In 2007, sceptics observed that Geller appeared to have dropped his claims that he does not perform magic tricks. Randi highlighted a quotation from the November 2007 issue of the magazine "Magische Welt" (Magic World) in which Geller said, "I'll no longer say that I have supernatural powers. I am an entertainer. I want to do a good show. My entire character has changed."
