Launched on the 22nd of July, 1999, Windows Live Messenger enjoyed pole position for a number of years when only a few competitors such as Yahoo! Messenger were around. Voice and video calling between computers was one of its main attractions in addition to text chat. However, the entry of Google's client and browser-based IM service managed to sweep away a sizeable number of users soon after it was launched a little over seven years ago. Probably to counter this new kid on the block, Microsoft and Yahoo! launched interoperability between their two IM clients to allow users from one service to chat using the other's client. Facebook Chat interoperability has also been supported since September, 2010. Nevertheless, it seems that the IM client finally decided that now is a good time to take a bow. Windows Live Messenger was reported to have over 330 million active users in 2009, although the number is now dropped to somewhere around 100 million.
How many of you use Windows Live Messenger as your primary IM client? Do you think this is a good move by Microsoft?
