ECMA was founded 1961-06-17 in Geneva. At that time , ECMA stood for European Computer Manufacturers Association.
In 1994, the organization became global and changed their name to Ecma international - European association for standardizing information and communication systems. (Note the shift from all-uppercase letters ECMA to only init-cap Ecma).
