Dolby Labs Marks 40th Anniversary

Dolby Laboratories --which got its start by improving the sound of recorded audio with its debut of Dolby A-type noise reduction--has turned 40 years old.

In 1972, Dolby introduced its first cinema products, the Model 364, and by end of the disco decade, had debuted its first multichannel audio technology, Dolby Stereo. "Star Wars" and "Close Encounters of the Third Kind" were two blockbuster movies to feature this technology. Today, approximately 78,000 Dolby cinema processors have been sold worldwide.

The company recently introduced Dolby Digital Cinema which was commercially launched in select cinemas worldwide with the release of "Star Wars: Episode III - Revenge of the Sith."

Dolby Digital has become the audio standard for Advanced Television Systems Committee (ATSC), DTV, HDTV, digital cable and digital broadcast satellite transmissions.

Dolby Digital Plus, Dolby Pro Logic IIx, Dolby Digital Stereo Creator, Dolby Digital 5.1 Creator, Dolby Digital Recording and MLP Lossless are all recent audio innovations that the company has rolled out.
