What is THX?
THX, an acronym for "Tomlinson Holman Experiment," is a renowned audio and video certification standard developed by THX Ltd., a subsidiary of the Dolby Laboratories. It ensures a high level of fidelity and immersive experience for audio and video content.

History of THX

The Origins: Lucasfilm and "Star Wars"
The roots of THX can be traced back to 1983 when George Lucas, the visionary behind the "Star Wars" franchise, sought to elevate the cinematic experience to a new level of realism and immersiveness. He founded THX, named after his sound engineer, Tom Holman, with the goal of delivering the same stunning audio and visual impact in movie theaters as he had achieved in the "Star Wars" films.
Early Days of THX in Cinema
