The History of Dolby


It all started in the 1960s with a sound compression and expansion system that reduced the level of background noise in film recordings.

Since then Dolby Laboratories has developed many innovative technologies, which have brought the reproduction of audio and video to a qualitatively new level.

And we’ll go back to Dolby and find out why this firm has become the most recognizable in the world.

The birth of sound: Dolby Stereo and Dolby Surround 

Dolby began in 1965, when the scientist Ray Dolby decided to devote himself entirely to sound and create his own business. One year later the young company launched its first product on the market – the A-Type professional noise cancellation system. Three years later was released the improved version – B-Type – already for the consumer market. The system was really unique for that time and soon the first cassette recorders equipped with it appeared. The next technical breakthrough was Dolby Stereo, which was a practical format for recording 4-channel sound on 35-millimeter tape. In 1977, Close Encounters of the Third Kind and Star Wars were released – both films had sound recorded in Dolby Stereo format. The tremendous success of these premieres also greatly contributed to Dolby’s entrenchment of the technology in the marketplace.

And when Lucas announced that the next movie from the movie saga will be shot in the same sound format, the Dolby Stereo technology began to be actively installed in theaters throughout the United States. A key feature of this system was its backward compatibility – the same phonogram could be played everywhere, from an old movie theater with monaural sound to a theater equipped with Dolby Stereo, thus eliminating the costly inventory of multiple tapes.

The success of Dolby Stereo led to the eventual abandonment of magnetic phono on 35mm film. Since then, magnetic sound has only been used on 70mm copies.

As early as 1982, Dolby introduced the Dolby Surround format, which was an adapted version of Dolby Stereo for the home market.

In 1987, CBS channel for the first time broadcast Super Bowl XXI in Dolby Surround format.
