To De Forest, the inventor of the audion was sold for $390,000.
In 1910 De Forest, an American inventor, had taken Fessenden’s system of broadcasting voice and used his triodes to broadcast the singing of Enrico Caruso. In 1916 he established a radio station and was broadcasting news. In the end De Forest sold his radio tube (or audion as he called it) to American Telephone and Telegraph Co. for $390,000 (a bargain at the price), but in the days of it s first development, he had his hard times. At one point he was placed under arrest for using the mails to defraud, when he was merely trying to raise cash to finance this invention. Like many inventors he was not a particularly successful business man. Often engaged in litigation, he lost fortunes as often as he made them. His triode, however, remained in undisputed command of the $90 billion dollar electronic industry it crated for a generation until Shockley’s transistor put it in the shade.
