When John Vincent Atanasoff in Ames, Iowa finished his electronic digital computer in early 1942 it was the only electronic digital computer in the world. Shortly after that he moved on to war related work and the university dismantled the machine to clear the basement where it was to add more classrooms. There were again no electronic digital computers anywhere in the world.

When Tommy Flowers of the British Post Office finished the Colossus Mark I electronic digital computer in December 1943 for Bletchley Park to help break the German High Command's cyphers, it was the only one in the world. However between June 1944 and June 1945 nine improved Colossus Mark II electronic digital computers were built and the original Colossus Mark I was upgraded to a Colossus Mark II. This was the only electronic digital computer produced in a quantity greater than one before the 1950s. In late June 1945 eight of the Colossus machines were ordered destroyed by Winston Churchill, the remaining two Colossus Mark II electronic digital computers were kept operating until about 1959 or 1960 breaking Soviet cyphers when they too were destroyed.

When Eckert and Mauchly, et al of the US Army's Project PX finished ENIAC in November 1945 it remained classified through December 1945 and January 1946 while it ran a simulation of Edward Teller's first Hydrogen Bomb design (called "The Super") for Los Alamos, showing that the design could not work. When ENIAC was declassified in February 1946 it became the only electronic digital computer known to the public (the two remaining Colossus Mark II electronic digital computers at Bletchley Park in England were still classified until the 1970s).
