1903: Nikola Tesla, a Yugoslavian who worked for Thomas Edison, patents electrical logic circuits called gates or switches.
1911: Computer-Tabulating-Recording Company is formed through a merger of the Tabulating Company (founded by Hollerith), the Computing Scale Company, and the International Time Recording Company.
1912: Institute of Radio Engineers (IRE) is formed.
1914: Thomas J. Watson becomes President of Computing-Tabulating-Recording Company.
1921: Czech word robot is used to describe mechanical workers in the play R.U.R. by Karel Capek.
1924: Computing-Tabulating-Recording Company changes its name to International Business Machines.
1925: Vannevar Bush, builds a large scale analog calculator, the differential analyzer, at MIT.
1927: First public demonstration of television. Radio-telephone becomes operational between London and New York.
1927: Powers Accounting Machine Company becomes the Tabulating Machines Division of Remington-Rand Corp.
1928: A Russian immigrant, Vladimir Zworykin, invents the cathode ray tube (CRT).
1931: Konrad Zuse builds First calculator, the Z1, in Germany.
1933: Dudley, who follows in 1939 with the Vocoder (Voice coder), builds first electronic talking machine, the Voder.
1936: Englishman Alan M. Turing while at Princeton University formalizes the notion of calculableness and adapts the notion of algorithm to the computation of functions. Turing's machine is defined to be capable of computing any calculable function.
