Future Developments Todays electronics industry isbuilt largely on an invention of LeedeForest in 1907: the three-element make a highly intricate electronic sys- vacuum tube.

Miniature apparatus components have been developed towork with the transistor. The transistor ttself is smallcompared to the smallest vacuum tubes. Resistors, ca-pacitors., transformers, inductors are all correspondinglysmaller than their counterparts used with vacuum tubes economy. It will make completelynew fields for itself as it begins to dowork where vacuum tubes have so farbeen excluded. Ultimately we shallsee transistors at work automaticallyrouting and connecting telephone callsthrough exchanges, doing accountingand computing, and performing inother so-called electronic brains.They are now appearing in hearingaids, and we shall soon see them inhome radio and television sets. The transistor, with all its promise,will come into large-scale use in theBell System only gradually. Otherfields of application—military elec-tronic systems, home entertainment. special services—may^well have the larger ini-tial uses. For in thesefields, particularly themilitary, it will now bepossibl
