Khronos Group

크로노스 그룹(Khronos Group)은 미국 오리건주 비버튼에 본사를 둔 비영리 산업체 컨소시엄이다. 로열티가 없는 개방형 표준 개발을 하고 있다. 다양한 플랫폼과 장치에서 동적인 미디어의 가속화된 재생 및 저작을 관련된 표준을 개발한다. 모든 크로노스 멤버들은 크로노스 API 규격의 개발에 기여할 수 있으며 공개적인 이용이 있기 앞서 다양한 단계에서 투표할 권한이 있고, 규격 초안과 적합성 테스트에 미리 접근할 수 있다.

2006년 7월 31일에 SIGGRAPH에서 OpenGL 표준의 관리를 크로노스 그룹에 이관한다고 발표하였다.
