THX

THX is a trade name of a high-fidelity sound reproduction standard for movie theaters, screening rooms, home theaters, computer speakers, gaming counsoles, and car audio systems. The current THX was created in 2001 when it spun off from Lucasfilm Ltd. THX stands for Tomlinson Holman's eXperiment and is a throwback to George Lucas' first feature film THX 1138. THX was developed by Tomlinson Holman at George Lucas' company, Lucasfilm, in 1983 to ensure that the soundtrack for the third Star Wars film, Return of the Jedi, would be accurately.
