With 400 million users, Facebook’s not the only online service doing incredibly well. Group Program Manager for social networking across Windows Live Jeff Kunins has posted some interesting news today with regard to Microsoft’s Windows Live Messenger service — 300 million users are now using Windows Live Messenger worldwide.

How ‘worldwide’ are we talking about? The service has penetrated into 76 countries around the globe in 48 different languages including Chinese, Estonian, English, Spanish, German, and Japanese. According to Kunins, Messenger users represent: 65% of all internet users in Brazil, 48% from Canada and Spain; 47% from France; 40% from Italy; and 39% from the UK.

Interesting facts:

• Every month, 163 billion minutes is spent on WLM, or 9.4% of all time consumers spend on the internet around the globe.
• 40%, or 130 million WLM users sign in each day.
• There are a total of 1.5 billion conversations daily, with 9 billion messages transmitted.
• At peak times, nearly 40 million users are signed on.

Windows Live Messenger’s success comes as a surprise to many Americans, considering the service hasn’t exactly been adopted here by many. Instead, we find folks chatting religiously over Facebook, MySpace, Gmail, and AOL Instant Messenger.
