Dolby Surround 7.1 is a sound system by Dolby Laboratories which delivers theatrical 7.1 surround sound to movie-goers. It adds two new channels to current Dolby Digital 5.1. The first film to feature Dolby Surround 7.1 was 2010's Toy Story 3 by Disney and Pixar.[1][2] While most theaters worldwide today still exhibit mainly in Dolby Digital, virtually every film that is released, as of January 2020, is mixed into Dolby Surround 7.1 by default, without even mentioning in the movie credits. Dolby 7.1 is mainly exhibited in premium large-screen formats, such as AMC ETX, Cinemark XD, and Dolby Cinema. As of January 2020, there are over 10,000 locations.
