THX was spun off from LucasFilm in 2001. Apparently 60% is now owned by Creative Labs which in 2011 made a huge loss and in 2012 managed to only get back into profit by selling of subsidiaries.
But I'd agree something is fishy...
Correct and Creative Labs are infamous for **** like this and were founded by a direct copy of other tech. Go look up the original Soundblaster card and then the AdLib card.
Also note that Creative has sued Apple before over the iPod interface (Apple settled for $100 million).
