Active Accessibility was initially referred to as "OLE Accessibility" and this heritage is reflected in the naming of its binary components such as codice_1 and the header file codice_2 which contains definitions and declarations. As part of Microsoft's ActiveX branding push in March 1996, OLE Accessibility was renamed ActiveX Accessibility (sometimes referred to as AXA) and presented as such at the Microsoft Professional Developers Conference in San Francisco, March 1996. Later, the ActiveX branding was reserved for internet-specific technologies, and ActiveX Accessibility became Active Accessibility and frequently shortened to MSAA.
