Beschreibung:

MSN Messenger (now Windows Live Messenger) is a proprietary client software linked to a proprietary instant messaging service (usable for free) for Windows XP, game consoles and mobile phones, and produced by Microsoft.

The concept was simple: software, installed on the user's machine, allowed him to know if knowledge to him - "his contacts" - were present on the internet and, if necessary, to be able to dialogue textually with them.
