PDF is now an international standard (ISO 32000) but it was invented by Adobe. HTML was invented at the CERN and is now controlled by W3C (a private consortium). OpenGL was created by SGI and is maintained by the Khronos Group.

Did you mean to type "does not" in that first sentence? Otherwise, the rest of your comment acts as evidence against it.
Yep, it was a typo. Thanks! Fixed.
