The first long-distance television transmission – from Washington, D.C., to New York City – is a notable first for Bell Labs.
Alsthom by Société Alsacienne de Constructions Mécaniques and Compagnie Française Thomson-Houston are formed.
Dr. Clinton J. Davisson becomes the first of 11 Nobel Prize winners from Bell Laboratories for his experimental confirmation of the wave nature of electrons.
After playing a critical role in providing communications and command equipment for the U.S. military during World War II, Western Electric is able to direct its efforts toward filling the pent-up demand for telephones, producing a record 4 million telephones.
- Reuse of radio frequencies among hexagonal "cells" is discovered, leading to cellular communications. In the mid-1940s, Bell Labs creates the cellular concept and developed the first commercial mobile telephone service.
- Bell Labs invents the transistor. Three Bell Labs scientists later received the Nobel Prize for their scientific breakthrough.

UNIX operating system is invented by Ken Thompson and Dennis Ritchie. A simple but elegant time-share software system for computers, it is designed to run on computers of all sizes, making open systems possible. UNIX later becomes the foundation for the Internet. The UNIX operating system and the C programming language, closely intertwined in both origin and impact, are created at Bell Labs between 1969 and 1972. UNIX makes large-scale networking of diverse computing systems -- and the Internet -- practical. The C language brings an unprecedented combination of efficiency and expressiveness to programming. Both make computing more "portable." Today, UNIX is the operating system of most large Internet servers, as well as business and university systems; C and its descendants are the most widely used programming languages in the world.
