In December 1947, John Bardeen, Walter Brattain, and William Shockley invented the transistor at Bell Telephone Laboratories in Murray Hill, New Jersey. This tiny semiconductor device could amplify and switch electrical signals without the fragile glass envelopes, high voltages, and excessive heat of vacuum tubes. The transistor, developed at Bell Labs' research facility in New Jersey, is considered one of the most important inventions of the twentieth century, enabling the miniaturization and democratization of all electronic technology.

The transistor's ability to amplify tiny electrical signals into powerful ones provided a metaphor that resonated in postwar American poetry's interest in the relationship between the small and the vast, the intimate and the universal. The Beat poets, writing in the transistor's early years, were implicitly responding to a world of miniaturized, portable technology that freed communication from fixed locations. Allen Ginsberg's "Howl" (1956), with its vision of electronic brains and neon, reflects a world already being reshaped by transistor technology, and the device's role in portable radios connected the Beats' street-level poetry to mass audiences.
