The International Standardization Organization (ISO) and the International Electrotechnical Commission (IEC) announced that Microsoft's Office Open XML (OOXML) will be the international standard document format. The OOXML format - used in Microsoft's Office 2007 - was chosen after much heated debate and a fair amount of mudslinging by parties opposed to and in favor of, to be the multi-platform standard used in spreadsheets, word-processing documents, and presentations. 104 countries participated in the joint ISO/IEC standardization process, which required a 66.67% "Yea" vote to approve OOXML.
