MSN is cross-platform instant-messaging client. It connects to the Microsoft Messenger service and is compatible with Yahoo!

Messenger and Facebook Messenger. The client was first released as MSN Messenger Service on July 22, 1999, and was marketed under the MSN brand until 2005, when it was rebranded under the Windows Live name. It has since been officially known by the latter name, although its first name remained in common use.
