Ninemsn is an Australian website owned by Mi9 in partnership with Microsoft. It was originally established as a 50:50 joint venture between Microsoft and PBL (later Nine Entertainment Company) in 1997. Microsoft sold its stake in the venture to Nine Entertainment Company in 2013
It serves as the main website for the Nine Network, and is the website that automatically appears when Australian users sign out of Outlook.com . While ninemsn was jointly owned by Microsoft, it also replaced the main MSN website in Australia. Microsoft have since developed an Australian version of MSN.
