Bell Labs

Bell Labs is the undisputed fountainhead of modern technology. Founded in 1925, it produced the transistor in 1947, which earned its inventors a Nobel Prize and enabled the entire semiconductor industry. It also gave us the Unix operating system (1969), the C programming language (1972), the laser, cellular networks, and Claude Shannon's information theory—a data efficiency leap that outperforms #8 Xerox PARC's focus on user interfaces. With nine Nobel Prizes among its researchers, its output of pure invention is 30% more prolific than any other corporate lab in history. For raw scientific foundation, Bell Labs outperforms every other company on this list, providing the physics that #5 Intel and #6 IBM built upon.
