For example, Massachusetts state government decided that in 2007 it would begin storing new records in a standard free of proprietary controls — namely, the OpenDocument format used in open-source software.
The groundswell threatened to hurt demand for Microsoft’s highly profitable Office products, which include such programs as Word and Excel.

Microsoft submitted the proposal with Ecma International, a Geneva-based industry group that establishes technical standards, and got backing from other players, including rival Apple Computer Inc.
