Both the title of the article (headline) and the statement you highlighted, are valid guesses. The number of citations of that paper was 275,669 as of January 2004; quite possibly over 300K by now. For comparison, the most cited article in CS, Rubin's paper on EM, has about 12K citations in ISI. What additional fields of academia (outside of science) did you have in mind?
