In 2011, journalist Debbie Nathan published a detailed exposé, "Sybil Exposed", in which she claims that Wilbur, Mason and Schreiber knowingly perpetrated a fraud in order to create a "Sybil, Inc." business, selling T-shirts, stickers, board games and other paraphernalia. Much of Nathan's book repeats material already covered in the original "Sybil", including a 1958 letter in which Mason spoke about making up the "alters" for attention and excitement. In "Sybil", this letter was interpreted as an attempt to put difficult, painful therapy on hold. Nathan claims Schreiber became aware of Mason and her alleged past, writing "Sybil" based on stories coaxed from her during therapy, and that this case created an "industry" of repressed memory.
