DLB

Dolby Laboratories, Inc.

A maker of audio and video technologies found in movie theaters, TVs, smartphones, and headphones, Dolby Laboratories licenses its sound and picture systems—like the immersive Dolby Atmos audio and high-dynamic-range Dolby Vision imaging—to electronics makers and studios. Physicist Ray Dolby founded the company in London in 1965 after tape hiss spoiled his recordings of sitar music in India, and he set out to build a noise-reduction system. The company's name comes straight from its founder's surname.
