The "20 times the number of adult bookstores" quote you cited comes from an article entitled "The Business of Pornography", written by Eric Schlosser, and published in the February 10, 1997 edition of US News & World Report.

And several posts previous to this, TJ has taken to complaining we are using his sources in our arguments! He himself has no tacitly admitted his sources are full of crap and not to be trusted.
