Herman Hollerith's company will eventually become IBM.…
June 1890 CE
He initially does business under his own name, as The Hollerith Electric Tabulating System, specializing in punched card data processing equipment.
He provides tabulators and other machines for the Census Office, a landmark in the history of computing hardware; it begins using the machines on June 1, 1890.
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—is to reduce the time required to process the census from eight years for the 1880 census to six years for the 1890 census.
