The worlds first commercially produced digital computer, UNIVAC, was released on this day in 1951.
The US Census Bureau took delivery of UNIVAC 1 (Universal Automatic Computer), on March 31 1951. The machine was officially dedicated "open for business" on June 14. It was developed by Presper Eckert and John Mauchly.
These early computers weren't the slimline desktops and notebooks users are accustomed to today; instead they used thousands of vacuum tubes and filled entire rooms.
Manufactured by Remington Rand, UNIVAC I weighed 16,000 pounds, used 5,000 vacuum tubes, and could perform about 1,000 calculations per second.
The complete system occupied more than 350 square feet of floor space, according to Wikipedia.
On November 4, 1952, the fifth commercially released model of the machine correctly predicted Dwight Eisenhower's unexpected victory in the presidential election.
