Standardization
The Web3D Consortium has been formed to further the collective development of the format. VRML (and its successor, X3D), have been accepted as international standards by the International Organization for Standardization (ISO).
The first version of VRML was specified in November 1994. This version was specified from, and very closely resembled, the API and file format of the Open Inventor software component, originally developed by SGI. The current and functionally complete version is VRML97 (ISO/IEC 14772-1:1997). VRML has now been superseded by X3D (ISO/IEC 19775-1)
