Wrong!
IBM did not want to build computers until 1951 a year after the UNIVAC I was already being sold.
The original invention occurred before 1945 on the then classifiedProject PX, to build ENIAC. But it was never recorded who came up with the idea.

∙ 11y agoAs the definition of supercomputer is a computer at least 10 times the speed and 10 times the storage of other computers of the same time period, other computers must precede supercomputers.
All early programmable computers were mainframes, as the vacuum tubes required lots of space.
Thus mainframe computers preceded supercomputers.
