Microsoft's Merchant Server (precursor to Commerce Server) was primarily written in Python and shipped in 1996. This is due to the fact that they acquired eShop for the software, a company co-founded by Greg Stein (who is pretty well known in the Python community). Python has been fairly well embraced by some parts of Microsoft for quite a while now, and while some of that support has come and gone over the years (eg. IronPython), they still have projects like Python Tools for Visual Studio which are very solid.
