Microsoft
In 1990, Microsoft introduced its office suite, Microsoft Office. The suite bundled separate productivity applications, such as Microsoft Word and Microsoft Excel. On May 22, Microsoft launched Windows 3.0, featuring streamlined user interface graphics and improved protected mode capability for the Intel 386 processor. Both Office and Windows became dominant in their respective areas.
Mathematical markup language
Microsoft Word included Equation Editor, a limited version of MathType, until 2007. These allow entering formulae using a graphical user interface, and converting to standard markup languages such as MathML. With Microsoft's release of Microsoft Office 2007 and the Office Open XML file formats, they introduced a new equation editor which uses a new format, "Office Math Markup Language" (OMML). The lack of compatibility led some prestigious scientific journals to refuse to accept manuscripts which had been produced using Microsoft Office 2007.
