Advocates' mission was to explain libertarian ideas to the public. Fritz found that Nolan's chart was a great help with explaining how libertarianism was distinct from conservatism and liberalism. He created the Quiz in 1987, and it was the first political Quiz posted on the Internet. The first form the Quiz took was as a business card, with the ten questions printed on it along with the chart. As of August 2004, over 7 million Quizzes had been printed. The Quiz, then, is a combination of two elements: Nolan's chart, and Fritz's idea of ten short questions to help a person find their associated place on that graph. The quiz has also been represented in other forms: reprinted in newspapers, used in classrooms, and recommended by leading high school and college textbooks. During 1993, Brian Towey, with the help of his wife Ingrid, produced a full-color, instant-scoring computer Quiz on disk, for the DOS and Windows operating systems. Programmer Jon Kalb created an equally advanced version for Macintosh computers. Toby Nixon created an ASCII text copy of the Quiz in the era prior to the World Wide Web, and this version was circulated in newsgroups, computer networks, bulletin boards, and on software. During 1995, Paul Schmidt created the Advocates' website, with the current interactive version of the World's Smallest Political Quiz. As of November 1, 2013, the online World's Smallest Political Quiz has been taken 20 million times since it was first put on the Web in 1995.
