The UNIVAC 1(1951)
P.Eckert and J.Mauchly left the EDVAC project to form their own company and built the UNIVAC I computer. UNIVAC stands for UNI\fersal Automatic Computer. The first UNIVAC was installed in the Census Bureau in 1951, and it was used continuously for 10 years. From the University laboratories the computer finally entered the wider world in 1951 with the invention of first UNIVAC I. It was the first digital computer which was not "one of a kind", it was produced in quantity. In 1952 IBM (International Business Machine) introduced the 701 commercial computer. Although limited in storage capacity by modern standards, the 701 could add a column of 10-digit numbers as tall as the Empire State Building in one second. Very soon improved models of the UNIVAC I and other 701-series machines were introduced. In 1953 IBM produced the IBM 650 which used a magnetic drum for storage and was popular with business and science.
