Basically, THX is a set of standards to which components and systems can be designed to meet. Initially developed by Lucasfilm, with much input from George himself, THX was intended to define a minimum standard of equipment and quality control that theaters would need to meet in order to become ‘certified’ as THX approved. The idea was to raise the overall quality and consistency of audio in movie theaters. And Lucasfilm had the clout to make such a certification mean enough from a marketing point of view that theaters wanted to support it and be certified. This also spawned an explosion of THX approved mixing rooms and dubbing stages. Subsequently it has been adopted as a standard in hi-fi equipment with many manufacturers licensing and producing certified THX components for home theater systems.
