MSN

    (MSN) Microsoft's ISP and online content
   service, launched in October 1996.  Not to be confused with
   Microsoft Networking.

   MSN was originally based on custom software and protocols,
   however Microsoft saw the error of their ways and adopted
   Internet standards.  MSN now provides standard WWW and
   email facilities, albeit with Microsoft's Internet
   Explorer web-browser and the Outlook Express email
   software.

   The service also provides "Community Services" including
   newsgroups, forums, and chat.
