It took some time before the full potential of the triode was realised.
Eventually it was de Forest who succeeded in using it as an amplifier and in
1912 he built an amplifier using two devices. This was demonstrated to AT&T who
understood its potential for use as a repeater in long distance telephone
circuits.
