1946
 EDVAC is designed
 The EDVAC, the electronic discrete variable computer, was the successor to the ENIAC.  It contained only 4000 vacuum tubes to the ENIAC’s 18,000 but was more powerful primarily because of its ability to store programs.  This was accomplished through mercury delay.  The architecture that the EDVAC was based on is the same that is used in the majority of computers today. 
 Although the EDVAC was not completed until 1952, the other computers completed around this time, including the UNIVAC and the EDSAC, were all based off of its design.  The EDVAC is important because it allowed for the storing of programs and developed an architecture that has been used in nearly every digital computer since that time. 
Next : 1954 - FORTRAN is created
