ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [ 3 ] [ 4 ] Other computers had some of these features, but ENIAC was the first to have them all.
The first digital electronic computer was developed in the period April 1936 - June 1939, in the IBM Patent Department, Endicott, New York by Arthur Halsey Dickinson. [35] [36] [37] In this computer IBM introduced, a calculating device with a keyboard, processor and electronic output (display). The competitor to IBM was the digital electronic ...
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
[citation needed] Maurice Wilkes and a team at Cambridge University executed the first stored program on the EDSAC computer, which used paper tape input–output. Based on ideas from John von Neumann about stored program computers, the EDSAC was the first complete, fully functional von Neumann architecture computer. 1949 Oct United Kingdom

A documentary, The World's First Computer, was produced in 2012 by the Antikythera mechanism researcher and film-maker Tony Freeth. [101] In 2012, BBC Four aired The Two-Thousand-Year-Old Computer; [102] it was also aired on 3 April 2013 in the United States on NOVA, the PBS science series, under the name Ancient Computer. [103]
A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. While the history of mechanical aids to computation goes back centuries , if not millennia , the history of vacuum tube computers is confined to the middle of the 20th century.
It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970, and was first sold in early 1971. Unlike a modern personal computer, the Kenbak-1 was built of small-scale integrated circuits, and did not use a microprocessor. The system first sold for US$750. Only 44 machines were ever sold, though it's said 50 to 52 were built.
