One technological advance which greatly impacted everyday life was the ability to transmit voice by radio instead of only coded messages, something which was made possible by the use of electron tubes as both oscillator and signal amplifier.  Although the basics of the technology were developed in the years before the war it was the necessities of the war which accelerated both the research and the actual use of this process on a continuous basis.The thermionic valve, or vacuum tube, was invented in 1904 by John Ambrose Fleming, so called because heat controlled the flow of electrons just as a mechanical valve controlled the flow of water.  The device converted Alternating Current to Direct Current, and was incorporated into his radio wave detector.  Lee deForest in 1906 refined the device into the triode tube, which greatly amplified radio waves.  But it was in 1912 that Edwin H. Armstrong used triodes to create a regenerative wave which could amplify radio waves to such a gain state that received waves could be heard through a loudspeaker, instead of only through earphones.  This allowed voice transmission, which while actually used before the war came into its own through the use of radio for communications by the German and British Navies.  Eventually the use of radio for communications spread to armies, and after the war became the basis of most of what we think of as “entertainment” today.  Radio, television, talking movies and vocal and instrument amplifiers all come from the expansion of this technology during the Great War.
