Microsoft Windows Live is an online applications services suite which presents tools such as Microsoft Office via a web browser interface. The product was released into Beta on Tuesday, November 1, 2005.
On the entry for Live.com (curiously, these are two separate articles) Wikipedia says:
In early November 2005, Live.com became a website by Microsoft, which aims to integrate all kinds of Microsoft web services, such as MSN Messenger, Hotmail and Anti-virus scanning into one single homepage.
Interesting. This seems to be a rival for Google’s customisable homepages. It’ll be interesting to see what happens with this service.
