In 2002, the THX division of Lucasfilm was spun off as a separate company, THX, Ltd. The same year, THX was owned by sound card manufacturer Creative Technology Limited, which held a 60% share of the company. The company has had a long history with Creative, which was responsible for the creation of the first THX-certified audio card for computers, the Sound Blaster Audigy 2.
In 2016, THX was acquired by video-game hardware company Razer Inc., with Razer owning all of THX and its intellectual property
The name THX is a reference to George Lucas' first feature film, THX 1138.
