UNIVAC I

(UNIVersal Automatic Computer) The first mass produced and commercially successful computer, introduced in 1951 by Remington Rand. Over 40 systems were sold. Comprising some 5,000 vacuum tubes and weighing nearly eight tons, the memory in the UNIVAC I was made of mercury-filled acoustic delay lines that held 1,000 12-digit numbers. Storage was magnetic tape reels that held 1MB of data at a density of 128 cpi.

In 1952, the computer predicted Eisenhower's victory over Stevenson, and, for a while, UNIVAC was synonymous with "computer." UNIVAC I machines were in use until the early 1960s. See delay line memory and early memory.
