<P> Hollerith initially did business under his own name , as The Hollerith Electric Tabulating System , specializing in punched card data processing equipment . He provided tabulators and other machines under contract for the Census Office , which used them for the 1890 census . The net effect of the many changes from the 1880 census : the larger population , the data items to be collected , the Census Bureau headcount , the scheduled publications , and the use of Hollerith 's electromechanical tabulators , was to reduce the time required to process the census from eight years for the 1880 census to six years for the 1890 census . </P>
