IBM Celebrates Banner Year 1947 Johnson City, NY “One Hundred Percenter Convention” In 1947 IBM announced an increase in revenue of 22% with an employment staff of over 22,000. One of IBMs innovative products is the Automatic Sequence Controlled Calculator, called the Mark I, a joint development with Harvard University. It is the first machine that can execute long computations automatically. Over 50 feet long, eight feet high and weighing almost five tons, the Mark I takes less than a second to solve an addition problem, six seconds for multiplication and twice as long for division. This year it was followed up by the 603 Electronic Multiplier, the next line of IBM machines.
