UNIVAC I
(UNIVersal Automatic Computer) The first commercially successful computer, introduced in 1951 by Remington Rand. Over 40 systems were sold. Its memory was made of mercury-filled acoustic delay lines that held 1,000 12-digit numbers. It used magnetic tapes that stored 1MB of data at a density of 128 cpi. In 1952, it predicted Eisenhower's victory over Stevenson, and UNIVAC became synonymous with computer (for a while). UNIVAC I's were in use up until the early 1960s. See delay line memory.
