In the USA de Forest, replicated Fleming's diode and went a stage further by adding an additional element to give a device he called and Audion. Although de Forest applied for several patents in the years between 1905 and 1907, the invention of the triode is normally taken to be 1906. Initially the triode was only used as a detector. Its operation was not understood, and this prevented its full potential from being utilised.
