PCR publication graph. This shows the dependence of use of the PCR technique as a function of availability of the Taq polymerase. The roughly linear increase in number of PubMed database entries for "PCR" (after about 1993) under-estimates the true use of the PCR technique. Many research articles use PCR without mentioning the term "PCR" in the title/Abstract/keywords that were searched to gather these data. The total as of March 2004 is close to 200,000.
