Ty Ahmad-Taylor has stepped down as president CEO of THX, the company announced, and is now product marketing VP of global marketing solutions at Facebook.

Min-Liang Tan, co-founder of THX parent Razer, will be CEO of both companies. THX was acquired by Razer in October 2016. Ahmad-Taylor joined THX in November 2015 to ensure healthy operations through the acquisition and transition process, according to the company, and he had reached the end of his contract.

THX chief technology officer Scott Francis, brought on as the first new hire after the merger, will continue in his role, as will Bill Rusitzky as chief revenue officer.

THX is a developer of A/V standards. It was founded by filmmaker George Lucas in 1983 but was later spun off.
