Entropy98 writes "Windows Live Messenger will be shut down by March 2013, after nearly 13 years of service, so Microsoft can focus its efforts on Skype, its recent $8.5bn acquisition. No word on whether users will be able to transfer their WLM accounts to Skype. 'According to internet analysis firm Comscore, WLM still had more than double the number of Skype's instant messenger facility at the start of this year and was second only in popularity to Yahoo Messenger. But the report suggested WLM's US audience had fallen to 8.3 million unique users, representing a 48% drop year-on-year. By contrast, the number of people using Skype to instant message each other grew over the period.'"
