Although new inventions are made so rapidly in the electronics field as to be considered almost every-day occurrences few are truly revolutionary in scope. The development of a new vacuum tube, transformer or capacitor, important as it may to be to one branch of the field, generally has little over-all affect on the industry.

But revolutionary inventions are occasionally made...one such development was the invention of the triode vaccum tube by DeForest. It is reasonably safe to say that the present-day radio, television and electronics industry has resulted from the application of this one invention and its modifications.
