The UNIVAC I was the first American computer designed to provide fast execution of relatively simple arithmetic and data transport operations for commercial purposes, as opposed to the complex numerical calculations required of scientific computers.

By adding offline card processing equipment, the UNIVAC was designed to compete with existing punch-card machines.

To promote sales, the Remington Rand Corporation joined with CBS to have UNIVAC I predict the result of the 1952 Presidential election. UNIVAC I accurately predicted an Eisenhower victory over Adlai Stevenson, the candidate pollsters favored. 

UNIVAC I used about 5,000 vacuum tubes, weighed 16,686 pounds, 7 consumed 125 kW, and could perform about 1,905 operations per second running on a 2.25 MHz clock.
