A UNIVAC I computer was accepted by the Bureau in 1951
UNIVAC
UNIVAC™ in 1951, when Remington Rand sold the first UNIVAC I to the US Census Bureau.
On March 31, 1951, the Census Bureau accepted delivery of the first UNIVAC computer. The final cost of constructing the first UNIVAC was close to one million dollars. Forty-six UNIVAC computers were built for both government and business uses.
The Remington Rand UNIVAC, it correctly predicted the 1952 presidential election on TV.
1951 - UNIVAC I by the US Census Bureau. Prior to this computers were custom designed on contract as one of a kind machines.
The UNIVAC I (UNIVersal Automatic Computer I) was the first commercial computer produced in the United States. It was designed principally by J. Presper Eckert and John Mauchly, the inventors of the ENIAC. Design work was begun by their company, Eckert-Mauchly Computer Corporation, and was completed after the company had been acquired by Remington Rand. (In the years before successor models of the UNIVAC I appeared, the machine was simply known as "the UNIVAC".) The first UNIVAC was delivered to the United States Census Bureau on March 31, 1951, and was dedicated on June 14 that year.[1] The fifth machine (built for the U.S. Atomic Energy Commission) was used by CBS to predict the result of the 1952 presidential election. With a sample of just 1% of the voting population it correctly predicted that Dwight Eisenhower would win. The UNIVAC I computers were built by Remington Rand's UNIVAC-division (successor of the Eckert-Mauchly Computer Corporation, bought by Rand in 1950).
The Census got S/N 1.
In the US the first UNIVAC I was sold to the Census Bureau for about 1/10 of what it cost to build, in 1951. Prior to this computers were not "sold" as products, but built as one of a kind machines on "cost + fixed fee" contracts.
Remington Rand made the first commercial computer called the UNIVAC in 1951. There first customer was the U.S. Census Bureau. It had over 50 thousand vacuum tubes (transistors were not yet invented).
It's IBM (AKA Lenovo), But I don't know the software.
UNIVAC meant UNIVersal Automatic Computer.UNIVAC was an electronic stored program digital computer designed by Eckert Mauchly Computer Company (EMCC). However due to mismanagement and gross underestimation of costs to build the machine EMCC was about to declare bankruptcy without having delivered even one of the four UNIVACs they had already contracted to build. Remington Rand (the electric shaver, typewriter, and firearm company) bought the failing EMCC and immediately negotiated cancellation of two of the UNIVAC contracts. The first two UNIVACs were delivered at the original contract price at a very significant loss, to correct this Remington Rand negotiated later UNIVAC contracts at gradually increasing prices until the price stabilized at about 10 times the original EMCC prices so that an acceptable profit could be made on each UNIVAC sold.The UNIVAC used 12 digit signed decimal numbers for both instructions and data (an optional modification allowed for packing two 6 digit short instructions per 12 digit word). Memory was a recirculating mercury acoustic delay line system based on mercury acoustic delay lines developed during WW2 for use on RADAR systems to remove stationary ground clutter from the screen. The UNIVAC circuitry was vacuum tubes.The first UNIVAC completed (built for the Census Bureau) was used before delivery to predict the 1952 Presidential Election. It correctly predicted an overwhelming win for Eisenhower very early when the companies doing surveys had incorrectly predicted an overwhelming win for Stevenson. This was so unexpected that the results were incorrectly reported on TV that UNIVAC was predicting a close win by Stevenson multiple times, however ultimately they were forced to report the real UNIVAC prediction and apologize for misreporting UNIVAC's real predictions.
